numpy.mat

numpy.mat(data, dtype=None)[source]

Interpret the input as a matrix.

Unlike matrix, asmatrix does not make a copy if the input is already a matrix or an ndarray. Equivalent to matrix(data, copy=False).

Parameters :

data : array_like

Input data.

Returns :

mat : matrix

data interpreted as a matrix.

Examples

>>> x = np.array([[1, 2], [3, 4]])
>>> m = np.asmatrix(x)
>>> x[0,0] = 5
>>> m
matrix([[5, 2],
        [3, 4]])
