MATLAB: How to find the integral of some values

excelintegral

Hello community!
I have a file on excel with some values which are the output signal. So, I want to find the integral of these values.
How to do that in Matlab or Simulink?
PS. I have imported the excel file on workspace
Thanks in advance!

use the trapz (or cumtrapz) function (depending on the result you want). It would be best to also have an independent variable (for example, time) as well as part of the integration, if you have access to it.
