Denis, How do you interpret the return cutoff variable? Also, how can I find the exact cuttoff value (the optimal cuttoff).

thanks :)

18 Jul 2008 Convert covariance matrix to correlation matrix Converts covariance matrix to correlation matrix setting exactly 1-s on its main diagonal Author: Denis k, denis

Example:

x = [0.1 0.2 0.3; .3 .5 .2; .5 .6 .2; .5 .2 .4];

[std, corMatrix] = cov2corr(cov(x));

diag(corMatrix) == 1

Really? Can you give an example of a non-unit-diagonal correlation matrix output by cov2corr?
