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 first half of the output. The output will be stored in one array of complex ...
In fact, one can process two real-to-real transforms in one complex-to-complex call. I can imagine the execution time being roughly equal if complex arithmetic is performed in parallel in the micro-architecture, but it would puzzle me if it is lower.My first question...

Beyond risky open surgical or endovascular intervention for large AAA, there is currently no proven pharmaceutical treatments to prevent AAA progression. The pathophysiology of AAA is highly complex, which is underpinned by an interplay of genetic risk factors, such as a positive family history and ...
