numpy.mat — NumPy v1.13 Manual (original) (raw)
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. dtype : data-type Data-type of the output matrix. |
|---|---|
| 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]])
