B_func(z, z_us) =

(ellipticF(theta, -(4*R_m*r)/((z - z_us)^2 - (R_m + r)^2)) - (ellipticE(theta, -(4*R_m*r)/((z - z_us)^2 - (R_m + r)^2))*((z - z_us)^2 - R_m^2 + r^2))/((z - z_us)^2 + (R_m - r)^2))/((z - z_us)^2 + (R_m + r)^2)^(1/2)

>> B = int(B_func, z_us)

matlab cannot solve this problem. Can you find how can I solve this integral?

Have you tried using integral() ? , please share the values of the missing datas.

It is not even remotely surprising that MATLAB cannnot find an analytical solution, as a function of all those unknown variables, in a fairly complicated expression. The only surprise is that you think it is even possible.

If you provide numerical values for those unknowns, then integral will surely succeed, not int.
