I have followed the instructions for using MatLab binaries directly.
-I have installed version 6.3.0 of MinGW_w64, and prepended the path to the binaries to the path environmental variable, both in CMD and in system settings.

• I have downloaded the sgpp_v3.1.0_matlab-windows.tar.gz file, and extracted the files to a directory and added that path in MatLab,
  When trying to run sgpp.Grid.createLinearGrid(2) in MatLab I get the following error:
  Invalid MEX-file 'C:\Users\Evan_S\SG\matsgpp\matsgppmex.mexw64': The specified module could not be found..
  Even though I can see this file in directory.
  Can you tell me how to fix this?
