sincd

sincd — digital sinc function or Direchlet kernel

Calling sequence

[s]=sincd(n,flag)

`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

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