May I please ask a question :) (Sorry if this is not the right place to do so.)

Is it possible to define a sparse circulant matrix in Julia? (For instance, a matrix stemming from the spatial discretization of a one-dimensional heat equation with periodic boundary condition.)
If so, how?

Thank you very much, in advance!

My suggestion is to modify Circulant in

https://github.com/JuliaMatrices/ToeplitzMatrices.jl

to support a storage format of SparseVector.
