LinearSolve Function

Posted 11 years ago
How Could I use the LinearSolve Function to solve large system of  equations. Attached are 2 examples in the first file (first.nb) the LinearSolve Function Works perfectly fine however when I try to include it with some other operations id doesn't work and it keeps running and at the end a message appears that no more memory is available. The file "Second..nb" shows the calculaton I am trying to run and the error message.

Sorry about the problems attaching files.  They are believed to have been fixed yesterday afternoon.  Please try again.

Something might be working for me, because I don't see any files. 

Could you describe in more detail your question? Yes it is possible to give LinearSolve a problem that is too large to be held in memory. You can use Sparse matrices when applicable to avoid this. Additionally, use Floating point numbers instead of rational/symbolic values to avoid using too much memory. 

Are you able to run smaller examples?
