sincd - digital sinc function or Direchlet kernel

Calling Sequence

[s]=sincd(n,flag)

Parameters

• n : integer
• flag : if flag = 1 the function is centred around the origin; if flag = 2 the function is delayed by %pi/(2*n)
• s : vector of values of the function on a dense grid of frequencies

Description

function which calculates the function Sin(N*x)/N*Sin(x)

Examples
