Fonction savemat - module scipy.io

Signature de la fonction savemat

def savemat(file_name, mdict, appendmat=True, format='5', long_field_names=False, do_compression=False, oned_as='row') 

Description

help(scipy.io.savemat)

Save a dictionary of names and arrays into a MATLAB-style .mat file.

This saves the array objects in the given dictionary to a MATLAB-
style .mat file.

Parameters
----------
file_name : str or file-like object
    Name of the .mat file (.mat extension not needed if ``appendmat ==
    True``).
    Can also pass open file_like object.
mdict : dict
    Dictionary from which to save matfile variables.
appendmat : bool, optional
    True (the default) to append the .mat extension to the end of the
    given filename, if not already present.
format : {'5', '4'}, string, optional
    '5' (the default) for MATLAB 5 and up (to 7.2),
    '4' for MATLAB 4 .mat files.
long_field_names : bool, optional
    False (the default) - maximum field name length in a structure is
    31 characters which is the documented maximum length.
    True - maximum field name length in a structure is 63 characters
    which works for MATLAB 7.6+.
do_compression : bool, optional
    Whether or not to compress matrices on write. Default is False.
oned_as : {'row', 'column'}, optional
    If 'column', write 1-D NumPy arrays as column vectors.
    If 'row', write 1-D NumPy arrays as row vectors.

Examples
--------
>>> from scipy.io import savemat
>>> import numpy as np
>>> a = np.arange(20)
>>> mdic = {"a": a, "label": "experiment"}
>>> mdic
{'a': array([ 0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14, 15, 16,
    17, 18, 19]),
'label': 'experiment'}
>>> savemat("matlab_matrix.mat", mdic)
