[source]

#

Notes

Same as

ndarray.mean

except that, where that returns an

, this returns a

matrix

object.

Examples

>>> x=np.matrix(np.arange(12).reshape((3,4)))>>> xmatrix([[ 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]])
