I didnt know this. Documentation doesn't mention this. 
Thanks.

I hope ur asking me what is the problem?
Im trying to obtain weights for each nucleotide at each
position for measured activity. I can use pinv or backslash
as discussed above if i use binary notation for describing
my (matrix M) set of sequences. Another way can be to
minimize residual sum of square from initial guessed values
for each weight. Not sure im answering ur question.
Thanks again.
