装了visual studio 2015，可是在matlab中调用失败了。

>> mex -setup

尝试去装SDK，还是不行。下面介绍一个可行的方法，也许对你有用。

>> gnumex1

会弹出一个GUI 框：

安装图中的选择好目录，最后点击Make options file,稍作等待几分钟，就OK了。

看结果：

>> mex -setup

Warning: Legacy MEX infrastructure is provided for compatibility; it will be removed in a future

version of MATLAB. For more information, consult the MEX release notes

Welcome to mex -setup. This utility will help you set up

a default compiler. For a list of supported compilers, see

http://www.mathworks.com/support/compilers/R2015a/win64.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler:

[1] gcc in D:\Rtools\GCC-46~1.3\bin

[0] None

Compiler: 1

Please verify your choices:

Compiler: gcc

Location: D:\Rtools\GCC-46~1.3\bin

Are these correct [y]/n? y

Trying to update options file: C:\Users\mingzi\AppData\Roaming\MathWorks\MATLAB\R2015a\mexopts.bat

From template: F:\matlab\bin\win64\mexopts\GNUMEXOPTS.bat

Done . . .

**************************************************************************

Warning: The MATLAB C and Fortran API has changed to support MATLAB

variables with more than 2^32-1 elements. In the near future

you will be required to update your code to utilize the new

API. You can find more information about this at:

http://www.mathworks.com/help/matlab/matlab_external/upgrading-mex-files-to-use-64-bit-api.html

Building with the -largeArrayDims option enables the new API.
