2. what is the difference between the full SVD and the compact SVD?

   the compact SVD has no zero singular values in its Sigma matrix. They are simply removed along with their corresponding rows and columns in U and V.T

3. In order to make the U matrix square again, we must add another column, and it must be orthornomal to the other columns already existing in U:
