I want to use cufft library for computing 1-D FFT along the columns of a matrix. I have successfully computed FFT along the rows using cufftPlan1d and cufftExecC2C. I think cufftPlanMany is going to work in this case, but not sure how to use it. Input vector is of type cufftComplex of size 4096 x 4096.
Any help in this case will be highly appreciated.
