Hello,

I have a time-domain sequence x[n]={x[0] x[1] ... x[N-1]}, which is periodic with period N, and I need to do some processing on it so that the conjugate of the processed sequence will be the conjugate of X[k], where X[k] is the DFT transformation of x[n]. This is the symmetry property in the DFT.

Mathematically, the sequence y[n]={x[0] x[N-1] ... x[1]} will be the processed sequence. In MATLAB the indices begin from 1. Will anything change?

Thanks in advance
