some problem with the mex file

[darkblue3699]

I run the script 'matRad_example1_phantom.m'. It shows the error that tell me the optimize mex file is invalid. But I have the ipopt.mexw64 file in the directory optimization/optimizer.

Which Matlab version are you using? the current ipopt.mexw64 may be incompatible to older Matlab versions (<2019).
If you have the optimization toolbox installed, you can also try to set pln.propOpt.optimizer = 'fmincon'; to optimize with the interior-point method implemented by Mathworks.

Thanks for your reply. My matlab version is 2016. I will change to new version Matlab.
