Asked by Passband Modulation on 21 Sep 2012

x[n]=n^3-n^2, 0<n<3

h[n]=1/n, -2<n<-1

y[n] is the convolution of x[n] and h[n]

how can i compute y[n] ?

With all due respect, I think you need to take some time to read the MATLAB documentation.

    n = 0:3;
    x=n.^3-n.^2;
    m=[-2:-1];
    h=1./m; 
    y = conv(x,h)
