spffrt2 issue

370 Views

I am trying to use mkl_dspffrt2, but it does not give a correct result. I used packed storage as recommended. The routine does not work for example for n=1 when A=[10], it generates [1]. According to manual should be 10. Or for A= {10,20,30} it generates A={0.1, 20, -0.1} which is wrong.
Have anyone used this routine?

Thanks,
