ifft scaling problem

Serjio — Wed, 09 Jun 2021 07:04:52 GMT

Hi.

I use Intel_oneAPI.win.BaseKit v2021.2.0,

Visual Studio 2019,

Windows 10.

When I use the Intel oneMKL ifft functions, I get the correct output, but the data is not scaled. In other words, the scaling function does not work:

double size = 32768.0; status = DftiSetValue (descriptor, DFTI_BACKWARD_SCALE, 1.0 / size); // Scale down the output

After that status = 0 but the scale is always 1.
What am I doing wrong??

I found a bug in my code. The function is working correctly. This topic can be closed
