numpy.matrix.argmin¶
- matrix.argmin(axis=None, out=None)[source]¶
Return the indices of the minimum values along an axis.
Parameters : See `numpy.argmin` for complete descriptions. See also
Notes
This is the same as ndarray.argmin, but returns a matrix object where ndarray.argmin 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.argmin() 11 >>> x.argmin(0) matrix([[2, 2, 2, 2]]) >>> x.argmin(1) matrix([[3], [3], [3]])
