Orthogonal random matrix - zulfiquar zab - May 29 20:41:12 2008



Hi,
 
  I want to generate orthogonal random matrix in matlab. 
How can I do it?
 
Cheers

Hello Zab,

You can try with "gallery" function to build test matrices. Check the full 
function reference at:

ref/gallery.html

Regards,
Mercedes.

hi zab.
do u mean uncorrelated matrix?
if so. yo u can try

a = randn(n,1);
b = randn(n,1);
x = cov(a,b);
cov = x(1,2);
c = (a - mean(a)) / std(a);
e  = b - cov * c;
f = (b - cov*a) / std(e);

good luck

kimbol
