I am tryng to solve a linear system with lsove(), with many variables being zero, so lsolve() tell that is indeterminate, but some of these entries are of interest. So, I am looking for matrix::solve and construct a matrix to solve this. Somebody have a piece of code how to make a linear system a matrix to matrix::solve ?

Please have a close look at the code in check/exam_lsolve.cpp and check/check_lsolve.cpp. It contains several regression tests for lsolve including over- and underdetermined linear systems. Regards -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>
