BigFloat support for TwoPointBVProblem using MIRK4

5

Using BigFloat with a TwoPointBVProblem and MIRK4 solver currently fails with the following error: > ArgumentError: matrix type SparseArrays.SparseMatrixCSC{BigFloat,Int64}not supported. Try lu(convert(SparseMatrixCSC{Float64/ComplexF64,Int}, A)) for sparse floating point LU using UMFPACK...

This package takes a massive amount of time to precompile (~100s) and most of that is due to the precompile workload. Removing the precompile workload makes it take 15s (and...

Singularity handling in MIRK methods

With the latest changes to nonlinear solve, several algorithms compute VJPs and they don't use $J^T v$ rather they use AD to differentiate the internal nonlinear problem, this causes significant...

This needs to be handled similarly to MIRK, but someone needs to go in and do it.
