Closed Issue: SparseMatrix doesn't add to/subtract from zero components [5666]
Hi,I noticed a bug using your otherwise quite nice library with sparse matrices.Currently, if you do the following:var m1 = new SparseMatrix(1, 3);var m2 = new SparseMatrix(new double[,] { { 0, 1, 1 }...

Could you post the positions of the "1" values for the 649 and 650 matrices? This would make it easier to test.Thanks, Marcus

Hi Marcus,As requested, here are the positions (as coordinates) of the "1" values in both matrices.649 (works) - http://txtup.co/CZtcC650 (fails) - http://txtup.co/kXzbRAs a bit of background, each...

The code never converges to a solution. There is an iteration count, but is is never used. The FORTRAN HQR2 code (what JAMA and this code seem to be based on) errors out if the number of iterations is...

Hi, Thanks for the help. So you have no ideas as to why the matrix doesn't converge, is there something wrong with the matrix itself? I could really do with being able to display the eigenvalues for my...

found that I could get the eigenvalues for 650 dimensions fine but then the same issue occurred with 672 Interesting, since both sets of code seem to be a port of the JAMA code but with a different...
