4、根据2生成的随机数作为输入,调用oneMKL API计算二维Real to complex FFT。 解决方法:参考最新版oneMKL工具中的DftiComputeForward( ) 函数,实现利用oneMKL API计算二维Real to complex FFT。 图4 调用DftiSetValue函数进行二维FFT 5、结果正确性验证,对3和4计算的二维FFT输出数据进行全数据比对(允许适当精度误差...
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...
this term refers to peculiar layout of the data in the frequency domain of1Dreal-to-complex transform. For one 1D half-complex result is laid out as all real parts followed by all imaginary parts in the reverse order (R0,R1,R2,...I3,I2,I1)...
