It is more efficient to do this without the loop: Theme. Copy. H = cumsum (h* exp (-1i*2*pi*fd));However, as the 1st values of eta1 and eta2 are zero, the rest of the values will also be zero, as the value of term n is directly proportional to the value of term (n-1) (observed from the formula/expression above)..
