是否有办法进行核查——与FFTW进行单一或双重汇编?
如果图书馆的名称有点,它就是一个精确的。 否则,这是双重的。 例如,

I am trying to do a batch FFT on 50 images using the following snippet: pix3 = n*pix1*pix2; fftwf_complex *in2, *f2h; //input for FFT2 in2 = (fftwf_complex*)fftwf_malloc(sizeof(fftwf_complex) * pix3);...
I take blocks of incoming data and pass them through fftw to get some spectral information. Everything seems to be working, however I think I m getting some aliasing issues. I ve been trying to work ...
I m working on some pitch correction software for Android, and I am looking to get fftw3 working on Android using the NDK. The pitch correction library (talentedhack, http://code.google.com/p/...
I would like to use FFTW3 on Windows-64 bit. I follow the instructions on FFTW website: download the package, unzip, run lib.exe to create .lib "import libraries". After doing so, I build my ...
I m using this fftw library. Currently I m trying to plot a 2D Gaussian in the form e^(-(x^2+y^2)/a^2). Here is the code: using namespace std; int main(int argc, char** argv ){ fftw_complex *in,...
I m trying to integrate the FFTW3 (a GNU FFT library written in C, http://www.fftw.org/) into an iPhone app. I downloaded the source code and I found there are hundreds of .h and .c files along with a ...
I m trying to link my project with fftw and so far, I ve gotten it to compile, but not link. As the site said, I generated all the .lib files (even though I m only using double precision), and copied ...
I m baffled by the results I m getting from FFT and would appreciate any help. I m using FFTW 3.2.2 but have gotten similar results with other FFT implementations (in Java). When I take the FFT of a ...
