`BCR(Y188_Y199~0,Y196_Y207~0) 2.997178348854e+05` the starting value in BCR isn't an integer. Are you sure this isn't just written for ODEs as concentration values?

BCR segfaults

This seems misguided. Will this just be the same as the type name that would then be used for better lowering. @YingboMa should we just add that first?

I think so. And it would make a `Val(:Resistor)` type information or something?

oh yes no val. But yeah, let's go this route.

That's not necessarily a good approximation and would converge as O(h) since it's equivalent to the maximum approximation given a linear interpolation. For a BVP intermediate solution, we don't just...

If you don't use MKL_jll, then most installations are about 10x slower. So we depend on it by default but allow for preferences to not load it. In theory, Preferences.jl...

Well it should check the retcode on the linear solver first, but yes it should report success if successful.

QR you probably just need to turn on pivoting.
