using convolution with matlab

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)

i did try, but i am not a good learner somehow...

anyway, thanks for ur kind replies. it really helps a lot!

You should accept people's answers if they help you.

Use the function conv()

See the help for conv()

ive tried, but it does not work at all.

 n=[0:3];
 x=n^3-n^2

 m=[-2:-1];
 h=1/m

 y= conv(x,h)

no results at all, could u help?
