Problem: Linker errors (LNK1120/LNK2001) if I compile my code with calling convention __vectorcall (/Gv) in Visual Studio 2015 and using C functions from MATLAB.

For example: "LNK2001 Unresolved external Symbol "matOpen@@16" "

Using a different calling convention /Gd, /Gr or /Gz the code compiles without any error. Linking with libs in the following Matlab dir ..\Matlab\R2015b\extern\lib\win64\microsoft\
