# scipy.io.mmwrite

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

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

  Parameters
    target str or file-like

      Matrix Market filename (extension .mtx) or open file-like object.

    a array like

      Sparse or dense 2-D 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.
