Hi everyone. I am having a problem and would like your help if
possible. I have a 101 X 101 and a 201X201 matrix which I want to
invert and am using solve to do it. I get a message which says the
matrix is apparently singular, but I know that it is not. Could it be
that the first matrix is 97% zeros and the second is 98.5% zeros?
