Normalize
in [Matlab]
|
From: Em M on 15 Jul 2010 18:59 Hi all, I need normalize and the correlation to matrix, and I use the function 'normxcorr2' of Matlab. But now, I can't use this function and I need to know if exist others functions that do the same. I have tried, first I have normalized with the equation: aP = sqrt(diag(p'*p)); PNormalized=p./(ones(size(p,1),1)*aP'); And then, I have done the correlation with the function 'xcorr2', c=xcorr2(PNormalized,B); But the result is not the same when I use the function 'normxcorr2'. I need help, please. Thank you.

You can normaliz data between [-1, 1] by using mapstd function For normalizing between [0,1], please look at the link below: http://www.mofeel.net/582-comp-soft-sys-matlab/98206.aspx Regards, Maitha
