matlab是非常好用的工具，大大简化了我们的开发难度，提高了实验效率。基本上是做研究的必备工具。但是一直很好奇matlab到底用到了哪些底层语言。折腾一段时间，在网上看到一个列表。Walking Randomly

• C (many built in compiled mex functions are written in C)
• C++ (MATLAB makes use of the Boost C++ libraries)
• CIL (Common Intermediate Langauge, used to be called MSIL, – The windows version of MATLAB uses this for various .NET stuff.  Thanks to ‘pmcs’ in the comments for this one)
• NVidia CUDA (Routines in the GPU part of the parallel computing toolbox)
• Bash shell script (On Linux, the startup ‘binary’ is a shell script)
• Fortran (MATLAB uses the MKL and I’m fairly sure this is written in Fortran)
• Java (Many of  the ticks in Yair Altman’s excellent book, Undocumented Secrets of MATLAB-Java Programmingmake use of the Java elements in MATLAB
• MATLAB (many MATLAB functions are written in .m code)
• Perl (Many mex-related scripts are written in Perl)
• Windows batch files (I’ve seen some simple .bat files as part of the mex machinery)
