Generate a matrix from linearly spaced vector

Hello,

I have the following line of code which generates a linearly spaced vector. How do I change it to a matrix of size m-by-n so that I can perform cov(log_sigma)? (covariance of noise matrix)

log_sigma=linspace(-2,2,30);

Thanks

doc reshape

N = 30 ;
log_sigma=linspace(-2,2,N);
m = 5 ; n = 6 ;
if m*n ~=N
  disp('you cannot reshape')
 break
else
  iwant = reshape(log_sigma,m,n)
end
