What have you tried? Have you tried int? Or integral? Or even just trapz?
The point is, this is not just a question about how to write that equation. First, you need to learn MATLAB. You need to learn the difference between those three subtly different tools in MATLAB. They are all there for very good reasons. The differences may seem sublte, but are important.
So start by learning enough about MATLAB to define the necessary constants. Decide how what is apparently a function w(q) will be created. Then decide what you will do with this expression, because no formula exists in a vaccuum. You have a reason to compute this. What will you do with it in the end? Do you want it in symbolic form? In numerical form? As a function you can evaluate or plot? How much accuracy do you need?
But until you do all of the above, you cannot reasonably just write that as some equation in MATLAB, and have it do anything useful at all.
