Hi,
Could you add information about the Preconditioner format.
If one use the Wikipeida convention (The Preconditioned Conjugate Gradient Method) , do you require $\boldsymbol{M}$ or $\boldsymbol{M}^{-1}$?
Looking at the code:
https://github.com/mcovalt/ConjugateGradients.jl/blob/12a23dd7d43177a15bb75508312386d43eed6108/src/cg.jl#L28
I assume you need a solver. Namely the function should return the solution to $\boldsymbol{M} \boldsymbol{z} = \boldsymbol{r}$.
