minres! crashes hard for a complex system #301
Comments
Can you provide something reproducible? I don't see this failing.
|
using LinearAlgebra, IterativeSolvers, SparseArrays A = sprand(19400, 19400, 0.1) + 1.0im * sprand(19400, 19400, 0.1) minres!(x, A, F; maxiter=20) blows up. |
@RaghuSivapuram can you share more details (os, cpu, julia version...) in JuliaLang/julia#40963? |
This problem doesn't occur in Julia 1.7. |
I am using minres! to obtain an improved solution than the given initial guess. The system matrices and the initial guess are complex.
I get this crash when I call: minres!(U, Kd, F; maxiter=20) where Kd, U are complex.

Please let me know if I'm misusing the function.
