Hi Bettina, I followed the following steps:
1. Download http://ab-initio.mit.edu/wiki/index.php/NLopt#Download_and_installation and the CMAKE files http://ab-initio.mit.edu/nlopt/CMakeLists.txt http://ab-initio.mit.edu/nlopt/config.cmake.h.in 2. Put the cmake files in the root folder of the source files 3. If using the CMAKE gui for windows - configure and generate the project using Visual studio Win64 generator (important step!) 4. Builld the project in VS (make sure its 64 bit!) 5. use the mex compilor on nlopt_optimize.c making sure to link it to the new dll you generated. Hope it helps, let me know if you run into any problems.
