Reconstruction based on the Pseudo-Inverse

The next approaches are based on the computation of the "pseudo-inverse" of tex2html_wrap_inline593. The first one computes the reconstruction matrix as follows:
By definition of the "pseudo-inverse" this matrix tex2html_wrap_inline615 minimizes tex2html_wrap_inline653.
