Circular shift dsp
WebIn mathematics, the discrete Fourier transform ( DFT) converts a finite sequence of equally-spaced samples of a function into a same-length sequence of equally-spaced samples of the discrete-time Fourier transform (DTFT), … WebY = circshift (A,K) circularly shifts the elements in array A by K positions. If K is an integer, then circshift shifts along the first dimension of A whose size does not equal 1. If K is a vector of integers, then each element of K indicates the shift amount in the corresponding dimension of A. Note

Create a column-vector col_vec of length K Insert the elements of the array H m into the col_vec in positions [0, m). As K = max (N, M), here N; M < K. Therefore fill the rest of the positions of col_vec [m, K) with 0.Therefore the col_vec will be col_vec = { 1, 1, 1, 0 }
