Hi, I`m wondering if I can use MKL FGMRES to solve Ax=B where all the elements in Matrix A and righthand vector are complex

FGMRES routines support only real data types so far.

Thanks a lot, and what could I do if I want to use GMRES to solve the liner system?

Hi,

You can split your system on new one with real values and doubled size by splitting initial on real and imaginary parts. Or you can use Intel MKL Pardiso (https://software.intel.com/en-us/mkl-developer-reference-c-pardiso) as solver of your system.

Thanks,

Alex
