numpy.matrix.argmax
-
matrix.argmax(axis=None, out=None)
[source] -
Indices of the maximum values along an axis.
Parameters: See `numpy.argmax` for complete descriptions See also
Notes
This is the same as
ndarray.argmax
, but returns amatrix

would return anndarray
.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.argmax() 11 >>> x.argmax(0) matrix([[2, 2, 2, 2]]) >>> x.argmax(1) matrix([[3], [3], [3]])
