I have a code for Newton Raph method to find x for nonlinear set of equations. The code works as I copy it, yet as I change the name of the function, and I save it appropriately, I receive this error: Undefined function 'Hamedani_solenoid' for input arguments of type 'syms' I have tried it several times but always the same error. I would appreciate any help in this respect. Thanks

if you are using a udf(user defined function) then the name of the function should be the same as the name of the m-file. try saving the file with the same name as the name of the udf. hope this helps

Thank you Qasim, I have tried this. I changed the path of Matlab and it works now. I do not have a good source/tutor to learn Matlab properly. do you have any suggestion? Thanks again
