Based on https://antennalab.upc.edu/en/acasolver-software
I have four files: ACA.m, user_impedance.m, user_impedance.c, and user_impedance.mexw64. Within user_impedance.m, the only computation is a function
Z = oper_3d_2_free(m,n,[ ],OG_data,field,k,eta,Rint_s,Ranal_s,Rint_f,corr_solid,flag);
that is not defined in user_impedance.c. I want ultimately to convert another function that calls user_impedance.m, ACA.m to a cpp source file. Using codgen results in an error where oper_3d_2_free is not defined whenever user_impedance.m is called.
Alternatively, if I could call the C version of oper_3d_2_free and get the returned impedance, I could complete the task.

Can you write a C function with your desired name and argument list, and pass that function to mex? See the documentation on mex, there are examples and you can probably easily change yprime.c so it does what you want.
