Currently, there are flavors of ippiMulPack and ippiMulPackConj for 1, 3, and 4 (with and without alpha channel processing). However, the other RCPack2D related functions ippiPackToCplxExtend, ippiCplxExtendToPack, ippiPhasePack, and ippiMagnitudePack either only support 1 channel (ippiPackToCplxExtend), or 1 and 3 channels (ippiCplxExtendToPack, ippiPhasePack, and ippiMagnitudePack). For completeness, please add the following functions to IPP, though the AC4 flavors are low priority (C3 flavors are high priority).
ippiPackToCplxExtend_32f32fc_C3R
ippiPackToCplxExtend_32f32fc_C4R
ippiPackToCplxExtend_32f32fc_AC4R
ippiCplxExtendToPack_32fc32f_C4R
ippiCplxExtendToPack_32fc32f_AC4R
ippiPhasePack_32f_C4R
ippiPhasePack_32f_AC4R
ippiMagnitudePack_32f_C4R
ippiMagnitudePack_32f_AC4R
Thanks,
