Decomposition matrix

The most intuitively candidate is to use the decomposition matrix tex2html_wrap_inline617: tex2html_wrap_inline619. By opposition with all the other methods investigated here, this is an a priori reconstruction, since it does not use tex2html_wrap_inline593 and tex2html_wrap_inline595. It will be considered as our reference method. Note that if the number of zeros is not constant in each column of tex2html_wrap_inline617, it has been shown in [Mayoraz-Moreira] that tex2html_wrap_inline631 should be normalized as tex2html_wrap_inline633.
