I have been using the ippiDFT* functions to do FFTs on real image data. These functions result in RCPack2D data, as described here: http://software.intel.com/sites/products/documentation/hpc/composerxe/en-us/ippxe/ipp_manual_lnx/hh_goto.htm#IPPI/ippi_ch10/ch10_real_complex_packed_rcpack2d_format.htm
I believe there are many errors in that table. For example, shouldn't the bottom left entry be 'Re A(M-1, 0)', not 'Re A(M/2, 0)'? Certainly it should be the same as the rest of the row. And, there should be only real components in the first or last columns, correct?
For what its worth, I've been able to implement my filters with correct resultsbased on what seems natural for the RCPack2D format to do if 2D DFTs are performe real->complex for the rows, then complex->complex for the columns (N/2+1 of them). If my understanding is correct, which gives correct results in practice using the functions, then this table has many errors.
