Im having a few issues trying to figure out the syntax to convolute two discrete impulse functions. any help on the syntax would be great. here are the two signals
x[n]= -delta[n+1] + 0.5delta[n] + 2delta[n-1] h[n]= 2delta[n] + delta[n-1]

i mean i don't know how to write the two signals in matlab. i know a little bit about the conv() function.

x[n]= -delta[n+1] + 0.5delta[n] + 2delta[n-1]
h[n]= 2delta[n] + delta[n-1]
"I don't know how to write the two signals in matlab"
So basically your signals are
x = [-1, 0.5, 2];
h = [1, 2];
You can convolve the two signals by using
y = conv(x, h);
Use the different options (under the heading 'shape' in the input arguments part) given in the help section and see which one is suitable for your use.
