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] ?

Accepted answer

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)

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?
