Hi Harsheel, thanks for you reply!
However, I just figured out what the mistake was:
\ipopt.mexw64 is refering to my NLP solver IPOPT.
It requires the libraries
- "Intel C++ Redistributable"
- "Intel Visual Fortran Redistributable"
- "Microsoft Visual C++ 2012 Redistributable"
I was using the solver with in my own 32bit Matlab, so I only had the 32bit versions of the libraries installed. After installing the 64bit versions the Matlab .exe was running as desired.
