    I've submitted some changes on the matrix class (and dependencies) today, so it now uses jagged arrays, as you suggested. Indeed, I observed nearly 50% perf improvement on the included small Solve perf analysis project. You may want to have a look at the changes first before updating your local SVN...

Interestingly I had just talked with another user about using jagged arrays instead of the rectangular ones some days ago... Looks like we'll have a new matrix base in the next iridium release :) Thanks, Chris PS: Are you...

  • Matrix class performance

    I have done some qualitative tests comparing different array types as storage for a Matrix class and have found that the rectangular array is the slowest possible way to implement the Matrix class. The other two options that I considered where jagged arrays (double[][]) and linear arrays(double[]) where...

    dear all, I came across math.net during a struggle to create and invert a very large matrix ( minimum= 5000x5000 and growing to 100000 x 100000) although some figures shown on the website look promissing, i am unable tocreate a matrix larger then 4000x4000 ad even that is with trouble. I keep gtting...
