the sparse IPM BPDN should be much faster than the dense ADMM...
not that it is a fair comparison
but it's also not fair to compare the two without also looking at the achieved accuracy

we have a dense matrix
does that mean that IPM BPDN is trying to create some kind of sparse matrix from our dense one? That would be horrible..

no, it is creating a larger dense matrix for the KKT system

Ah that makes sense.
Should ADMM have decent accuracy?
