numpy.matrix.max — NumPy v1.15 Manual (original) (raw)

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

Return the maximum value along an axis.

Notes

This is the same as ndarray.max, but returns a matrix object where ndarray.max would return an ndarray.

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.max() 11 x.max(0) matrix([[ 8, 9, 10, 11]]) x.max(1) matrix([[ 3], [ 7], [11]])
