I need to integrate my function, written in phyton 'trapz(Vz, Vt, r^2,r)/trapz(Vz^2,r,r)' that contains multiple variables with respect to r. I tried to solve it in Matlab using trapz function as well but there was an error when I tried to write in matlab for denominator 'trapz(r,trapz(r,Vz^2))'- I think this is for double integration and definitely wrong and have no idea how to do for the numerator.

Can someone help me with this function so that I can have the same solution in Matlab. Vz and Vt are changing values for each r position, and r is from -92 to 92. However, the interval between r is unequally distributed, where r = [92,87,82,77,67,52,37,22,7,0,-7,-22,...,-92].

Thanks.
