Matlab编程很容易上手，但运算速度很慢。主要原因是运行Matlab程序时候必须打开
Matlab软件，占用了很多系统资源。
看到Matlab网上的Matlab Compiler的介绍，它能把Matlab程序直接转成可执行文件。
不知是否有人用过这个软件，效果如何？
此外，如果不用这个Matlab compiler,是否有类似的工具可以把Matlab程序转换成C, C
++,或可执行文件？
谢谢

matlab运行慢是因为他是解释语言。

the complier can wrap Matlab's m file to exe file. However, the .exe file
still need to call the matlab engine.So, the speed is the same. The reason
to use complier is to protect your copyright of the program, since people
can not access your original code.
If you want to accelerate your matlab program, you can use mex function,
which is able to run the core operation parts(time consuming parts) in the
similar speed as C or Fortran.

compiling m function to exe file can speed up your code.
In my case, I observe it is about 3 times faster than m file.
But not sure in other cases.

anyway,based on my own experience, the difference is not much:), if you cons
idering 10 to 100 times speed acceleration by mixing C/Fortran and Matlab.
another bad thing for matlab exe file is that should be distributed with the
mrcinstaller, which is too huge, if the destination machine doesn't have Ma
tlab.Also the version of the Matlab in the origin and destination machine ne
ed to be compatible.
