I perfomed a PCA on dataset using the function
Then I generated new shapes (in the cartesian space) using a reduced number of principal components. Now I need to the principal component scores for these new shapes, but I can't figure out how!
Based on the fact that the original centered training data can be retrieved using
I used the following statements, which did not generate relevant results.
for i= 1:newShapesNum
I also tried running a pca analysis on the new instances, and requested [score] and [coeff]. The mean shape looked good but using the centeredData formula above did not regenerate the original shape! I don't understand why though..
I'd appreciate your help in finding the principal component scores for the new shapes.
