What do you mean by "the inverse of SVD"? The SVD is a decomposition: A = U*S*V' so reconstructing A just requires performing the multiplication.

If I set data as my input image %svd: [u,s,v] = svd(data) data_new1 = u*s*v'; %pca [coef,score] = pca(data); data_new2 = (score')*data;
Are data_new1 = data_new2?
