numpy.matrix.mean — NumPy v2.3.dev0 Manual (original) (raw)

method

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.

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) matrix([[4., 5., 6., 7.]]) x.mean(1) matrix([[ 1.5], [ 5.5], [ 9.5]])
