Méthode numpy.matrix.argmin

Signature de la méthode argmin

def argmin(self, axis=None, out=None) 

Description

argmin.__doc__

        Indexes of the minimum values along an axis.

        Return the indexes of the first occurrences of the minimum values
        along the specified axis.  If axis is None, the index is for the
        flattened matrix.

        Parameters
        ----------
        See `numpy.argmin` for complete descriptions.

        See Also
        --------
        numpy.argmin

        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]])
