Optimal way to resize matrix

1

Hi, is there any recommended way to resize sparse matrixes? Thinking about backing storage i would think coo matrixes should be easier to resize right?

Do you have an example of how to do an efficient scalar multiplication of a COO matrix somewhere? And one for vertically stacking two matrices similarly to Dense.Stack in gonum?

When assigning a value to a CSR (might be others too, but I know that one), how do we set the value back to 0.0? From https://github.com/james-bowman/sparse/blob/master/blas/matrix.go#L39, we can see...

For some sparse matrix formats, pivot operations can be done effectively without explicitly carrying out the matrix multiplications between the pivot matrix and the sparse matrix. This PR implements in-place...
