Incorporating Procrustes to PCA

Hi:

So I have a PCA matlab GUI. It can perform Jackknifing for displaying a training and prediction cloud plot of the data. The plot doesn't look good because it doesnt perform the rotation well. I want to add procrustes code to it to make it work but i'm finding it difficult in getting around it. The procrustes code is

[d, Z, transform] = procrustes(tdata,tdata)

Below is the code i want to add procrustes to:

colcode_temp = colcode;
            if jackState == 2 %training cloud mode
                for i = 1:size(tdata,1)
                    for j = 1:size(jknife,1)
                        plotMe(size(Xmean,1)+size(jknife,1)*(i-1)+j,1) = jknife(j,i,1);
                        plotMe(size(Xmean,1)+size(jknife,1)*(i-1)+j,2) = jknife(j,i,2);
                        colcode_temp(size(Xmean,1)+size(jknife,1)*(i-1)+j,:)=0.7; %turn all cloud points gray
                    end
                end

What is the question being asked?

@Walter Roberson I wanna know how to add the Procrustes code. Anytime I add it it doesn't seem to effect the results I want. The Procrustes code is supposed to conform tdata to itself and give Z which is a transformed form of tdata and then plot tdata agains the Z. I want a situation where when I click tcloud button in my gui it will excecute the Procrustes part as well

[Walter Roberson]

If you

 [d, Z] = procrustes(tdata,tdata)

you would get back a linear transform -- that is, Z is always going to equal tdata in that case.

You should be using procrustes with two different sets of data.
