Hi, I'm trying to use MKL to facilitate multidimensional convolution. For a same piece of code, 2D convolution works with direct mode but gives all zero with FFT mode. Is there any examples or tips on using this feature? Many thanks.
I was able to do a 2D convolution by
... code fragment ...
int mode = VSL_CONV_MODE_DIRECT;
vslsConvNewTask( &task, mode, dim, xShape, yShape, zShape );
status=vslsConvExec( task, signal, xStride, kernel, yStride, result, zStride );
However, if the mode is set to VSL_CONV_MODE_FFT; the result is all zero. And the task execution returns with error: status = -2000
