How to numerically integrate a vector over time?

I'm trying to obtain flux density in a iron core from my measurements. I've measured the data v(t) with the corresponding t values in vectors. How can I integrate v(t) with respect to t to obtain flux phi(t) and not just get a value of the integration? In other words, I need the result of the integration to be a vector of same length, not a numerical value.

If you want the cumulative integral of your vector, use the cumtrapz function.
