This routine computes a scaling 23 % for a giving matrix, e.g. a training set and applies it to other 24 % matrices, e.g. the same training set or based on a test set. 19 25 20 26 % Copyright: Elzbieta Pekalska, ela.pekalska@googlemail.com … … 41 47 %DEFINE mapping 42 48 if isstr(opt) 43 discheck(D);49 % discheck(D); 44 50 opt = lower(opt); 45 51 if strcmp(opt,'mean')
