Hello, From a certain correlation matrix accompanied by p-values [r, p], I need to extract a new matrix where all those correlation co-efficients which are positive and significant at some predefined level (e.g., p<0.01) are set to 1 and all the rest are set to zero. Hence, the new matrix will be in binary form.
Could anyone help?
BR, Muhammad

>> [r p] = corr(randn(10)); % Your actual r and p would go here instead.
>> new_r = zeros(size(r))
>> new_r(r>0 & p<0.01) = 1;
