Error in third mandatory.

In the section

Implementation: how is PCA implemented?

  PCA Algorithm

The text given in the function pca() states that pca_eigvec should have the shape (m eigenvectors, M dimensions). This is wrong, it's should be the other way around (M dimensions, m eigenvectors).

The assignment have been updated, and all the links to it on this site should now point to the new version.

This is the only change in this version and should not impact the code in any of the other sections.
