sub2ind.m -- trying to use with a 2D matrix

1 vue (au cours des 30 derniers jours)

I have a matrix
data = rand(100,100);
I also have a index into that matrix
IDY = randperm(100);
I wish to reorder the data matrix by the order in IDY.
I thought sub2ind could help me, but I have not been able to get it working.
FYI: the matrix is a correlation matrix. Each element refers to a variable. I wish to "re-order" the correlation matrix according to the ordering in IDY.
thank you
