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.

在 MATLAB Online 中打开

 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.
