Run a MuPAD script in matlab

I want to be able to evaluate the integral

int_R^\infty exp(2*I*k*r)/r^n dr

in MuPAD where the notebook must take R, k and n as input argument and return the value of the integral to matlab.

I have tried

f = evalin(symengine, 'float(int(exp(2*I*k*r)/r^n, r=R..infinity))'); matlabFunction(f, 'file','otherFunctions/expIntegral_syms')

but the function meijerG does not exist in matlab, so I do not get any resulting value.

The problem I guess is that I try to create a matlab function which evaluates the integral, but I want to evaluate the integral using MuPAD. How do I create a "function" in MuPAD which may transfer input and output arguments to matlab?
