+"""This modules defines a set of background model functions and associated
+estimation functions in a format that can be imported into a
+:class:`silx.math.fit.FitManager` object.
+
+A background function is a function that you want to add to a regular fit
+function prior to fitting the sum of both functions. This is useful, for
+instance, if you need to fit multiple gaussian peaks in an array of
+measured data points when the measurement is polluted by a background signal.
+
+The models include common background models such as a constant value or a
+linear background.
+
+It also includes background computation filters - *strip* and *snip* - that
+can extract a more complex low-curvature background signal from a signal with
+peaks having higher curvatures.
+
+The source code of this module can serve as a template for defining your
+own fit background theories. The minimal skeleton of such a theory definition
+file is::
+
+    from silx.math.fit.fittheory import FitTheory
+
+    def bgfunction1(x, y0, …):
+        bg_signal = …

+    This file provides a background strip function, to isolate low frequency
+    background signal from a spectrum (and later substact it from the signal
+    to be left only with the peaks to be fitted).
+
+    It is adapted from PyMca source file "SpecFitFuns.c". The main difference
+    with the original code is that this code does not handle the python
+    wrapping, which is done elsewhere using cython.

+/*  strip(double* input, double c, long niter, double* output)
+
+    The strip background is probably PyMca's  most popular background model.
+
+    In its simplest implementation it is just as an iterative procedure depending
+    on two parameters. These parameters are the strip background width w, and the
+    strip background number of iterations. At each iteration, if the contents of
+    channel i, y(i), is above the average of the contents of the channels at w
+    channels of distance, y(i-w) and y(i+w),  y(i) is replaced by the average.
+    At the end of the process we are left with something that resembles a spectrum
+    in which the peaks have been "stripped".
+
+    Parameters:
+
+        - input: Input data array
+        - c: scaling factor applied to the average of y(i-w) and y(i+w) before
+          comparing to y(i)
+        - niter: number of iterations
+        - deltai: operator width (in number of channels)
+        - anchors: Array of anchors, indices of points that will not be
+          modified during the stripping procedure.
+        - output: output array

+"""This modules provides a set of fit functions and associated
+estimation functions in a format that can be imported into a
+:class:`silx.math.fit.FitManager` instance.
+
+These functions are well suited for fitting multiple gaussian shaped peaks
+typically found in spectroscopy data. The estimation functions are designed
+to detect how many peaks are present in the data, and provide an initial
+estimate for their height, their center location and their full-width
+at half maximum (fwhm).
+
+The limitation of these estimation algorithms is that only gaussians having a
+similar fwhm can be detected by the peak search algorithm.
+This *search fwhm* can be defined by the user, if
+he knows the characteristics of his data, or can be automatically estimated
+based on the fwhm of the largest peak in the data.
+
+The source code of this module can serve as template for defining your own
+fit functions.
+
+The functions to be imported by :meth:`FitManager.loadtheories` are defined by
+a dictionary :const:`THEORY`: with the following structure::
+
+    from silx.math.fit.fittheory import FitTheory
+
+    THEORY = {
+        'theory_name_1': FitTheory(
+                            description='Description of theory 1',
+                            function=fitfunction1,
+                            parameters=('param name 1', 'param name 2', …),
+                            estimate=estimation_function1,
+                            configure=configuration_function1,
+                            derivative=derivative_function1),
+
+        'theory_name_2':  FitTheory(…),
+    }
+
+.. note::
+
+    Consider using an OrderedDict instead of a regular dictionary, when
+    defining your own theory dictionary, if the order matters to you.
+    This will likely be the case if you intend to load a selection of
+    functions in a GUI such as :class:`silx.gui.fit.FitManager`.
+
+Theory names can be customized (e.g. ``gauss, lorentz, splitgauss``…).
+
+The mandatory parameters for :class:`FitTheory` are ``function`` and
+``parameters``.
+
+You can also define an ``INIT`` function that will be executed by
+:meth:`FitManager.loadtheories`.
+
+See the documentation of :class:`silx.math.fit.fittheory.FitTheory`
+for more information.

+
+    Sum of hypermet functions, defined by
+    (area, position, fwhm, st_area_r, st_slope_r, lt_area_r, lt_slope_r, step_height_r).
+
+    - *area* is the area underneath the gaussian peak
+    - *position* is the center of the various peaks and the position of
+      the step down
+    - *fwhm* is the full-width at half maximum of the terms
+    - *st_area_r* is factor between the gaussian area and the area of the
+      short tail term
+    - *st_slope_r* is a parameter related to the slope of the short tail
+      in the low ``x`` values (the lower, the steeper)
+    - *lt_area_r* is factor between the gaussian area and the area of the
+      long tail term
+    - *lt_slope_r* is a parameter related to the slope of the long tail
+      in the low ``x`` values  (the lower, the steeper)
+    - *step_height_r* is the factor between the height of the step down
+      and the gaussian height
+
+    Parameters:
+    -----------
+
+        - x: Independant variable where the functions are calculated.
+        - len_x: Number of elements in the x array.
+        - phypermet: Array of hypermet function parameters:
+          *(area1, position1, fwhm1, st_area_r1, st_slope_r1, lt_area_r1,
+          lt_slope_r1, step_height_r1, ...)*
+        - len_phypermet: Number of elements in the phypermet array. Must be
+          a multiple of 8.
+        - y: Output array. Must have memory allocated for the same number
+          of elements as x (len_x).
+        - tail_flags: sum of binary flags to activate the various terms of the
+          function:
+
+              - 1 (b0001): Gaussian term
+              - 2 (b0010): st term
+              - 4 (b0100): lt term
+              - 8 (b1000): step term

+This module implements a Levenberg-Marquardt algorithm with constraints on the
+fitted parameters without introducing any other dependendency than numpy.
+
+If scipy dependency is not an issue, and no constraints are applied to the fitting
+parameters, there is no real gain compared to the use of scipy.optimize.curve_fit
+other than a more conservative calculation of uncertainties on fitted parameters.
+
+This module is a refactored version of PyMca Gefit.py module.

+This module provides a function and a class to compute multidimensional
+histograms.
+
+
+Classes
+=======
+
+- :class:`Histogramnd` : multi dimensional histogram.
+- :class:`HistogramndLut` : optimized to compute several histograms from data sharing the same coordinates.
+
+Examples
+========
+
+Single histogram
+----------------
+
+Given some 3D data:
+
+>>> import numpy as np
+>>> shape = (10**7, 3)
+>>> sample = np.random.random(shape) * 500
+>>> weights = np.random.random((shape[0],))
+
+Computing the histogram with Histogramnd :
+
+>>> from silx.math import Histogramnd
+>>> n_bins = 35
+>>> ranges = [[40., 150.], [-130., 250.], [0., 505]]
+>>> histo, w_histo, edges = Histogramnd(sample, n_bins=n_bins, histo_range=ranges, weights=weights)
+
+Histogramnd can accumulate sets of data that don't have the same
+coordinates :
+
+>>> from silx.math import Histogramnd
+>>> histo_obj = Histogramnd(sample, n_bins=n_bins, histo_range=ranges, weights=weights)
+>>> sample_2 = np.random.random(shape) * 200
+>>> weights_2 = np.random.random((shape[0],))
+>>> histo_obj.accumulate(sample_2, weights=weights_2)
+
+And then access the results:
+
+>>> histo = histo_obj.histo
+>>> weighted_histo = histo_obj.weighted_histo
+
+or even:
+
+>>> histo, w_histo, edges = histo_obj
+
+Accumulating histograms (LUT)
+-----------------------------
+In some situations we need to compute the weighted histogram of several
+sets of data (weights) that have the same coordinates (sample).
+
+Again, some data (2 sets of weights) :
+
+>>> import numpy as np
+>>> shape = (10**7, 3)
+>>> sample = np.random.random(shape) * 500
+>>> weights_1 = np.random.random((shape[0],))
+>>> weights_2 = np.random.random((shape[0],))
+
+And getting the result with HistogramLut :
+
+>>> from silx.math import HistogramndLut
+
+>>> n_bins = 35
+>>> ranges = [[40., 150.], [-130., 250.], [0., 505]]
+
+>>> histo_lut = HistogramndLut(sample, ranges, n_bins)
+                           
+First call, with weight_1 :
+
+>>> histo_lut.accumulate(weights_1)
+
+Second call, with weight_2 :
+
+>>> histo_lut.accumulate(weights_2)
+
+Retrieving the results (this is a copy of what's actually stored in
+this instance) :
+
+>>> histo = histo_lut.histo
+>>> w_histo = histo_lut.weighted_histo
+
+Note that the following code gives the same result, but the
+HistogramndLut instance does not store the accumulated weighted histogram.
+
+First call with weights_1
+
+>>> histo, w_histo = histo_lut.apply_lut(weights_1)
+
+Second call with weights_2
+
+>>> histo, w_histo = histo_lut.apply_lut(weights_2, histo=histo, weighted_histo=w_histo)
+
+Bin edges
+---------
+When computing an histogram the caller is asked to provide the histogram
+range along each coordinates (parameter *histo_range*). This parameter must
+be given a [N, 2] array where N is the number of dimensions of the histogram.
+
+In other words, the caller must provide, for each dimension,
+the left edge of the first (*leftmost*) bin, and the right edge of the
+last (*rightmost*) bin.
+
+E.g. : for a 1D sample, for a histo_range equal to [0, 10] and n_bins=4, the
+bins ranges will be :
+
+* [0, 2.5[, [2.5, 5[, [5, 7.5[, [7.5, 10 **[** if last_bin_closed = **False**
+* [0, 2.5[, [2.5, 5[, [5, 7.5[, [7.5, 10 **]** if last_bin_closed = **True**
