Closed Issue: Matrix serialization [5683]
Just as a comment - I checked out the latest code, added the Serializable attributes to all Matrix and DenseMatrix classes, and serialization works as a charm. Very happy :-). If you get a chance to...

Hi,I'm still using your nice library and I've found a little bug again, this time in the SubMatrix() method for sparse matrices.If you do something like this:var matrix = new SparseMatrix(10, 10,...

View ArticleEdited Feature: Modulo operator on matrix and vector [5662]
Hi - Is there a modulus operator on a matrix? More specifically, I'm creating a matrix: var matrixA = new DenseMatrix(new[,] { { 5.0, 8.0 }, { 17.0, 3.0 } });and I would like to perform the following...

I had occasion to create a very large, but narrowly banded matrix, on the order of 100k by 100k. I found that member-wise item setting using At() failed due an internal step where 'rows * columns' is...
