Hi, I have a speed problem running matrix operations like Dot[...] and LinearSolve[...] on large sparse numerical matrices. Currently I'm using Linux-Mathematica 4.2. I noticed that the new Mathematica 5 promises to be much faster on this kind of problems than version 4.2 (http://www.wolfram.com/products/mathematica/newin5/performance/sparselinear.html). But since I don't have the chance to upgrade to Rel. 5 yet, I wonder if there still is a smart way to speed up large sparse matrix operations under Mathematica 4.2 ?! Can anybody help ??? Many thanks Justus
