Column-wise FFT using cufftLibrary How to perform a column-wise FFT without performing a transpose.

Dear developers!

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.

Regards
