$[$Matlab$]$ Consider the following sequence $x(n)=sinc(cn),0n<mi\; id="EditorElement\_515816">|</mi><mi\; id="EditorElement\_515818">|</mi>$ where $c$ and $N$ are user defined constants.

a$)$ Write a matlab code to compute N$-$point DFT of the sequence $($use matrix$-$vector form$),$

b$)$ Develop a matlab code to find the windowed sequence $h_w[n]=x[n]w[n]$ where
