A matrix is normalized by dividing each entry [i,j] by the square root of the product of the diagonal entries [i,i] and [j,j]. The input matrix should be a square matrix with positive diagonal entries.
Usage
mat.norm(mat)
Arguments
mat
numerical matrix to be normalized
Value
The normalized matrix is returned.
