status = DftiSetValue(fft_handle, DFTI_COMPLEX_STORAGE, DFTI_REAL_REAL); If you care about time taken by calls to MKL FFT routines, please look at examples/dftc/source/basic_dp_real_dft_1d.c (I assume that you use MKL 11) which explains how to compute only the fir...
I use complex-to-complex transforms because I actually need two real-to-real transforms, backward and forward.everything else in the code is O(n) so the FFTs are the bottleneck. I was hoping for experience users or Intel engineers to give me the long an...

"complex forward domain"; - the set of real :math:`d`-dimensional periodic sequences, referred to as "real forward domain". Similarly, we refer to DFTs of complex (resp. real) forward domain as "complex DFTs" (resp. "real DFTs"). Regardless of the type of forward domain, the back...

After polyploidization, proplatelet formation begins, which involves complex cytoskeletal rearrangements,23 and is a prerequisite for platelet release. To better understand the mechanism by which the RBM15-MKL1 translocation causes defects in megakaryocytic differentiation associated with AMKL, we need to ...
