Are there any modules that provide access to (sparse) symmetric indefinite solvers with Bunch-Kaufman-Parlett pivoting where I can access the
D matrices, or would it be useful to build a module that does this? Right now, I have to do something like this.
As of now, is compiling IPOPT with the HSL linear solvers (for example, HSL_MA57) the easiest way to currently use the HSL routines? I saw a previous post build a custom IPOPT with these solvers, but if I only want to call the Bunch-Kaufman-Parlett
LDLt factorization (MA57), can I access it through IPOPT, or is there a more direct way? Btw, as another alternative, Pardiso doesn’t yet allow you to access the
