numpy.matrix.prod — NumPy v1.13 Manual (original) (raw)

matrix. prod(axis=None, dtype=None, out=None)[source]¶

Return the product of the array elements over the given axis.

Refer to prod for full documentation.

Notes

Same as ndarray.prod, except, where that returns an ndarray, this returns a matrix object instead.

Examples

x = np.matrix(np.arange(12).reshape((3,4))); x matrix([[ 0, 1, 2, 3], [ 4, 5, 6, 7], [ 8, 9, 10, 11]]) x.prod() 0 x.prod(0) matrix([[ 0, 45, 120, 231]]) x.prod(1) matrix([[ 0], [ 840], [7920]])
