I am currently trying to optimize a nanoantenna using the FDTD module.
Since I am using nonlinear constraints, I tried to do the optimization in Matlab, as explained here, but when I try to run it, Matlab just shows the error
Mex file entry point is missing. Please check the (case-sensitive) spelling of mexFunction (for C MEX-files), or the (case-insensitive) spelling of MEXFUNCTION (for FORTRAN MEX-files). Invalid MEX-file 'C:\Program Files\Lumerical\FDTD\api\matlab\appopen.mexw64':
The file does exist, and even when running the script as administrator the error shows up. I am using Matlab R2014b and the newest Lumerical version.
Is this due to a version incompatibility or is there another way to resolve this?
I appreciate every answer
