Unlike matrix, asmatrix does not make a copy if the input is already
a matrix or an ndarray. Equivalent to matrix(data, copy=False).
Input data.
Data-type of the output 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]])
