Hi people, I noticed that Mathematica 5 had an upgrade on sparse matrices. Anybody know if it's any good? I wasn't very impressed with the v4.2 approach using functions like a[_,_]=0;a[1,2]=1, etc. Also, have anyone seen some sparse-matrix algebra package for v4.2? I anticipate my institution will take a while to get the upgrade done, and I'm sort of in a hurry to get sparse matrices up & working... --- Roland Nilsson IFM Computational Biology Linköping University, Sweden rolle at ifm.liu.se
