I use the cuFFT library calls in a host code they work fine, but I want to call the cuFFT library from a kernel. Earlier versions of the CUDA didn't have this kind of support but with the dynamic p...

I am currently working on a program that has to implement a 2D-FFT, (for cross correlation). I did a 1D FFT with CUDA which gave me the correct results, i am now trying to implement a 2D version. W...

I'm using the following macro for CUFFT error handling: #define cufftSafeCall(err) __cufftSafeCall(err, __FILE__, __LINE__) inline void __cufftSafeCall(cufftResult err, const char *file, const int...

I'm trying to compute batch 1D FFTs using cufftPlanMany. The data set comes from a 3D field, stored in a 1D array, where I want to compute 1D FFTs in the x and y direction. The data is stored as sh...

Whenever I'm plotting the values obtained by a programme using the cuFFT and comparing the results with that of Matlab, I'm getting the same shape of graphs and the values of maxima and minima are ...

I'm experimenting with using cuFFT's callback feature to perform input format conversion on the fly (for instance, calculating FFTs of 8-bit integer input data without first doing an explicit conve...
