如何设置matlab 编译器 mex

Answer 1

mex -setup
Please choose your compiler for building external interface (MEX) files:

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

Select a compiler:
[1] Lcc-win32 C 2.4.1 in D:\Programs\MATLAB\R2010a\sys\lcc
[2] Microsoft Visual C++ 2005 SP1 in D:\Program Files\Microsoft Visual Studio 8
[3] Microsoft Visual C++ 6.0 in C:\Program Files\Microsoft Visual Studio

[0] None

Compiler: 2

Please verify your choices:

Compiler: Microsoft Visual C++ 2005 SP1
Location: D:\Program Files\Microsoft Visual Studio 8

Are these correct [y]/n? y

Trying to update options file: C:\Documents and Settings\Administrator\Application Data\MathWorks\MATLAB\R2010a\mexopts.bat
From template: D:\Programs\MATLAB\R2010a\bin\win32\mexopts\msvc80opts.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:

Building with the -largeArrayDims option enables the new API.

Answer 2

通常有兰特（平均随机数），randn（正态分布的随机数），并依此类推。点击看详细种子属性可以通过种子进行设定，如：点击看详细>> randn（“种子”，0）;
>> randn（5）
