WebWhen using complex numbers, use Pytorch with CUDA 11.6 downloaded via pip wheel as described in Get Started and select the CUDA 11.6 pip package. Complex numbers are numbers that can be expressed in the form a + bj a+ bj, where a and b are real numbers, and j is called the imaginary unit, which satisfies the equation j^2 = -1 j 2 = −1. WebYou can plot the real and imaginary components from the FFT result separately (or the magnitude and the phase results separately, as two plots). Then you can recombine the data from the two plots into a complex spectrum required to do a reconstruction IFFT.
