I have a vector / matrix I'm trying to numerically integrate and add to another vector, like so:
B= [1, 2, 3];
C = [8, 5, 4];
A = B + C(dt) <-- C being numerically intergrated with a timestep of 0.5. from 1 to 2000
I'm not sure what line or how to even go about writing this in my code, let alone plotting the data. Any help would be appreciated.

Use the trapz function (or cumtrapz, dependng on the result you want), The vector with respect to the numeric integration (time or whatever) is the first argument, and governs the integration steps.
