I would appreciate any test cases you might have.

Here is one such test case:

Help optimizing IPFP algorithm

I’m trying to speed up this version of the IPFP algorithm, which alternates between solving 2 systems of nonlinear equations until convergence: using NLsolve using LinearAlgebra const szAge = 64 - 19 + 1 const szE = 2 const β = 0.92 const δ = 0.10 maxT(am, af; Z=realage(szAge)) = Z - max(am, af) + 1 realage(x) = x + 18 realageinv(x) = x - 18 const IDX_ae = CartesianIndices((1:szAge, 1:szE)) @views function insideproduct(am, em, af, ef; μ0m=μ0m, μ0f=μ0f, Sm=Sm, Sf=Sf) prod(abs((μ0m[am +…
