row or column block permutation
[j]=jmat(n,m)
number of block rows or block columns of the matrix
size of the (square) blocks
(m*n,m*n) matrix with m*m eyed blocks
This function yields a square matrix j
of size (m*n, m*n) that can be used for permuting the n blocks of m consecutive columns of a (m*n, m*n) square matrix W by W*j. For permuting the n
blocks of m
consecutive rows, use: j'*W
