Im getting the following Error Message:

E:\GIT IRT\work\slprj\_sfprj\OptimizeTrajectory\_self\sfun\src\Files\MATLAB\R2016b\extern\lib\win64\mingw64 not found; check that you are in the correct current folder, and check the spelling of 'E:\GIT IRT\work\slprj\_sfprj\OptimizeTrajectory\_self\sfun\src\Files\MATLAB\R2016b\extern\lib\win64\mingw64'.
gmake: *** [OptimizeTrajectory_sfun.mexw64] Error -1
With "E:\GIT IRT\work\" being my working folder, I think that the error is that matlab is trying to find the folder of MinGW somewhere in my working folder.
Matlab is trying the path "E:\GIT IRT\work\slprj\_sfprj\OptimizeTrajectory\_self\sfun\src\Files\MATLAB\R2016b\extern\lib\win64\mingw64" which is not existing.
MinGW is under MatlabRoot\extern\lib\win64\mingw64, which is similar to the wrong path.
I have no idea how to fix this problem. I'm grateful for ideas.

Can you run "mex -setup" and follow instructions to select your local MinGW as the C compiler.

Hello, thanks for your answer.
If I type in "mex -setup", It states that a MinGW compiler (C) is present. Additionally the compiler was In the first lines of the error successful.

Right. Try removing the folder \slprj in your working folder and re-run. It is a temporary folder, safe to remove.
