I am trying to compile FFTW3 to run on ARM Neon (More precisely, on a Cortex a-53). The build env is x86_64-pokysdk-lunix, The host env is aarch64-poky-lunix. I am using the aarch64-poky-linux-gcc co...

I'd like to use FFTW in Armadillo.My code is: tuple<mat,mat> solver(mat charge) { mat x = regspace(0, mesh_num - 1); mat xx = reshape(x, 1, mesh_num); mat xxx = repmat(xx, mesh_...

I'm trying to learn how to use the FFTW library with Eigen. I don't want to use Eigen's unsupported module since I'd eventually like to incorporate FFTW's wisdom features into my code. However, I'm st...

In head files of simd of fftw3, such as simd-generic128.h and simd-generic256.h, STM2, STN2, STM4, STN4 are decleared. What operation do they do in fftw? I found that some of them lack implementations...
