MATLAB: How to create a variable name from parts of another variable name

Question

Let's say I have 2 vectors called time34578 and disp34578. Now I want to create a new vector vel34578 using displacement and time to compute. But I'm doing this in a script so I want to build the array name vel34578 not physically type it. How?
