The professional version of Microsoft Visual Studio C/C++ is officially supported for use with MATLAB.
We have seen some cases where using the Standard Edition has caused problems, such as not optimizing code. According to the Visual Studio 6.0 documentation, "Code optimization is supported only in Visual C++ Professional and Enterprise editions." The -Oy- switch turns off a particular optimization that the more generic -O2 optimization switch turns on.
If you would like to use the Standard Edition, remove the -O2 and -Oy- flags from your mexopts.bat. This may slow down the speed of your compiled code. Since we do not test with the Standard Edition of Microsoft Visual Studio, it is possible that you may run into other undesired behavior.
