On my system it is possible to invert up to 87*87 matrices with J and widows on a PC. I believe excell goes to something like 64*64. Of cause SAS and GAMS can go higher, but
Is it possible to get J to invert larger matrices? May be as Sparse? As you may have guessed the LAPACK lab did not work on my PC. I can download it to the add on area, but a call from the LAPACK lab results in an error. Is there a solution to that? Error in jijs_jctrl_fkey.. Best wishes Med venlig hilsen Henning P.
