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 a matrix object where ndarray.argmax 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.argmax() 11 >>> x.argmax(0) matrix([[2, 2, 2, 2]]) >>> x.argmax(1) matrix([[3], [3], [3]])
