The functions described in this section perform the element-wise complex multiplication of vectors stored in Pack or Perm formats. These functions are used with the function ippsFFTFwd and ippsFFTInv to perform fast convolution on real signals.
The standard vector multiplication function ippsMul can not be used to multiply Pack or Perm format vectors because:
- Two real samples are stored in Pack format.
- The Perm format might not pair the real parts of a signal with their corresponding imaginary parts.
Note
The vectors stored in CCS format can be multiplied using the standard function for complex data multiplication.
