I'm dealing with large linear systems which I have to solve. LinearSolve does it ok, but I'm looking for a faster solution, so the questions are:
1. Will Mathematica4 do it much faster than Mathematica 3 with LinearSolve?
2. The Book says that one should use NSolve when the matrices are sparse, but since my equations system is very large, it's impossible to write every equation or so.
What is recommended in this case?
Thanks a lot!!!
