High performance extension for sparse matrices.
- General Permutation Matrix
PermMatrix, - Identity Matrix
IMatrix, - Coordinate Format Matrix
SparseMatrixCOO, - Static Matrices
SSparseMatrixCSC,SPermMatrixet. al.
with high performance type conversion, kron, and multiplication operations.
Install with the package manager, pkg> add LuxurySparse.

Sid = id |> SparseMatrixCSC
@benchmark kron(Spm, Sid) # compare the performance to the previous operation.
spm = pm |> staticize # convert to static matrix, notice that `id` is already static.
@benchmark kron(spm, spm) # compare performance
