scipy.io.mmwrite¶

scipy.io.mmwrite(target, a, comment='', field=None, precision=None, symmetry=None)[source]¶

Writes the sparse or dense array a to Matrix Market file-like target.

Parameters:

Parameters:	target : str or file-like Matrix Market filename (extension .mtx) or open file-like object. a : array like Sparse or dense 2D array. comment : str, optional Comments to be prepended to the Matrix Market file. field : None or str, optional Either ‘real’, ‘complex’, ‘pattern’, or ‘integer’. precision : None or int, optional Number of digits to display for real or complex values. symmetry : None or str, optional Either ‘general’, ‘symmetric’, ‘skew-symmetric’, or ‘hermitian’. If symmetry is None the symmetry type of ‘a’ is determined by its values.
