Please post what you have tried so far and the error message, if you get one.

Did you try it?

A = 1:8000;
B = 1:5;
C = conv(A, B);

Seems pretty straightforward. What was the difficulty you had?

i tried this......i get this error "Matrix dimensions must agree."

No, you didn't try that. Because I know for a fact that that works, as long as you didn't redefine conv to be a variable or custom function, thus destroying the built-in conv(). You tried something else but didn't show us what your code was or what your error message was. Please paste your code and all the red text from the error message. Don't leave anything out.
