how to convolute two discrete impulse functions

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.

thank you very much! i got it to work.

Please! how we can plot each signals x, h and y ?
