`scipy.io._mmio:MMFile.read`

Signature

def read(self, source, *, spmatrix = <object object at 0x0000>)

Reads the contents of a Matrix Market file-like 'source' into a matrix.

source : str or file-like: Matrix Market filename (extensions .mtx, .mtz.gz) or open file object.
spmatrix : bool, optional (default: True): If True, return sparse matrix. Otherwise return sparse array.
deprecated 1.18.0
The default value for spmatrix is changing to False in v1.20. That means the default return value will be a sparse array. Unless you use * instead of @, ** for matrix power, or you depend on 2D shapes from e.g. A.sum(axis=0) it may not matter to you. See Migration from spmatrix to sparray.

a : ndarray or coo_array or coo_matrix: Dense or sparse array depending on the matrix format in the Matrix Market file.
