Why MKL-FFTW3 library could not be called in ABAQUS subroutine

WebMatlab uses FFT from the Intel MKL (Math Kernel Library) binary (mkl.dll). These are routines optimized (at assembly level) by Intel for Intel processors. Even on AMD's it seems to give nice performance boosts. FFTW seems like a normal c library that is not as optimized. Hence the performance gain to use the MKL.
