.SH "Detailed Description"
.PP 
This depends on Metal\&.framework\&.
.PP
\fBA\fP logarithmic softmax kernel that operates on matrices\&.
.PP
\fBA\fP \fBMPSMatrixLogSoftMax\fP object computes: 
.PP
.nf
            B_ij = ln { Exp { A_ij } / ( Sum_k Exp { A_ik } ) } = A_ij - ln { Sum_k Exp { A_ik } }

        A and B are matrices which are represented by MPSMatrix
        objects. This filter computes the same result for MPSMatrices as
        MPSCNNLogSoftMax filter does for MPSImages by interpreting the columns
        of the matrix as feature channels, that is the sum runs over column indices.
