The vector potential solution for circular current loop is given in (5.37) of "Classical Electromagnetics". J D Jackson, this solution has arguments of elliptic integrals

K(k) = INT{ dt/sqrt((1-t^2)(1-k^2*t^2)} for t[0,1]

The argument k is a spatial function of x, y and z. K(k) is a definite integral. t is the integrand, 0 to 1.

Please how do I DEFINE such integral in COMSOL40a Definitions node? And evaluate the vector potential?

My second question, I have a MATLAB routine for this vector potential. Can I and how do I DEFINE this MATLAB code in COMSOL40a?
