https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/GGEVX/m-p/914577#M12455 When I use the Fortran95 interface for the routine GGEVX I get an error message following this call: ! CALL GGEVX(A, B, ALPHAR, ALPHAI, BETA, BALANC = BALANCE, & ABNRM = A_NORM, BBNRM = B_NORM, RCONDE = RCONDE, INFO = INFO) The message is that argument no. 26 in DGGEVX is wrong, this is LWORK. If I skip the calculation of RCONDE the problem disappears. BALANC = "B" in the above call. The test matrices A and B are 2x2. I use MKL 10.0.2 and IVF 10.1.019.
