preserving sparse matrices (Matrix)
Hi,
I have sparse (tridiagonal) matrices, and I use the Matrix package for
handling them. For certain computations, I need to either set the
first row to zero, or double the last row. I find that neither
operation preserves sparsity, eg
> m <- Diagonal(5)
> m
5 x 5 diagonal matrix of class "ddiMatrix"
[,1] [,2] [,3] [,4] [,5]
[1,] 1 . . . .
[2,] . 1
