Double integration inside a for loop

Hi,

I am working with vectors and the whole script I have been using for loops to calculate the next vector and so on. In my problem I have several measurements which are arranged into vectors, thus each value in the vector represents a measurement.

Now I am to perform a double integral for each value in the vector. I assume I have to have a for loop outside the double integral to get a resulting vector. How do I do this?

I have R_wave(i), zeta_A(i) and an E(i). The formula I wish to code is attached as a photo.

I found this problem hard to formulate, so please let me know if something is unclear.

If you take a look at the example "Multiple Numerical Integrations" under

https://de.mathworks.com/help/matlab/ref/trapz.html

does this help ?

Best wishes

Torsten.
