PCA

The important method is [COEFF,SCORE] = princomp(x) which takes in your data “x” and stores its projection into PCA space in “SCORE” which I then output to csv. I still need to find out how to project back into normal space but I think it should be just as straightforward as this was. For more info on “princomp” type “help princomp” into matlab and have a look at the help files.
