I want to use biplot after a PCA analysis in MATLAB. I want to have the scaled score values in a separated vector. As I managed to see, biplot scales score values. How can I accede to this scaled data storing it in a separated matrix? How can I reproduce these scaled points without biplot? MATLAB says: "Scales the scores so that they fit on the plot. That is, the function divides each score by the maximum absolute value of all scores, and multiplies by the maximum coefficient length of coefs. Then biplot changes the sign of the score coordinates according to the sign convention for the coefficients." I do not understand what "the maximum coefficient length of coefs" is. Any help would be greatly appreciated.
