[Ported Issue] Why define IOSparseMatrix instead of MSparseMatrix? #2

Open chessai opened 6 years ago

Why is it that Data.Eigen.SparseMatrix.Mutable defines IOSparseMatrix a b instead of a MSparseMatrix a b s that can be used in the ST monad? Are the sparse matrix operations exported by Eigen not pure?

Reformatted to reflect new API:
