Double precision 2D FFT?

Are there no double precision 2D FFT functions in IPP? I can't seem to find them anywhere.

Will the FFT and DFT functions that take 64fc inputs work for your application?

To get there again:

- go to the IPP main page:

http://www.intel.com/software/products/ipp

- from there choose the

- then choose the HTML link for

- open Transform functions

- open Fourier Transform functions

- open Discrete fourier Transform Functions

- select DFTFwd_CtoC

Hope this is what you're looking for,

these functions only implement a 1-dimensional FFT. I suppose I could loop over all rows and all columns while calling this function in order to get a 2-dimensional FFT but I don't find the prospect very appealing. Are there plans for double precision FFT in the image processing library any time soon?
