matrix.mean(axis=None, dtype=None, out=None) [source]
Returns the average of the matrix elements along the given axis. Refer to numpy.mean for full documentation. See also numpy.mean Notes Same as ndarray.mean except that, where that returns an ndarray, this returns a matrix object. 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.mean()
5.5
>>> x.mean(0)
