I have the vectors of time (T) and voltage (V).

According to the following expression:

% integral from 0 to t of voltage V in dt = k * i (t)

where:

k = known constant; (unit measure: A*V^-1*s^-1)

i(t) = current intensity as a function of time.

How can I numerically integrate in Matlab the voltage V to get i(t)?

I would use the cumtrapz function.

It worked with median.

Thank you so much, you have been very helpful with both answers!
