I don't know what is the answer; i know that in the example I gave, p-value obtained with corrcoef aren't 0, but 1. Secondly, a...

So the only difference is in how P is calculate? x=0:0.1:10; y=x.^2+rand(1,101); plot(x,y) X=[x(:),y(:)]; [a,b]=corrcoef(X) [c,d...

Dear all, i have a very stupid question: what is the difference between [r,p]=corr(X) and [r,p]=corrcoef(X)? it seems that...

You might just sloghtly modify it; take your matrix M,transform it in a column ( M(:) ) and sort it. Then you can modify uniqu...
