Hello everyone! I'm working on Linux system. There are some C codes written on windows and used in matlab with mex, but it seems that mex is not available on Linux... Could anyone tell me how can I run C codes with matlab on Linux? Thanks a lot.

 Hi,

C code can be compiled in Linux using the mex command. Ensure that you have gcc installed in your machine. If you are compiling the C code for the first time, run the following command to see which compiler is used to compile the C code.

mex -setup

You can also refer to the following example to Create C Source MEX Files.

sorry to bother another time... due to some reasons I gave up using shared library and need to use MEX files. I just followed the tutorial you gave me and it just doesn't work... I just ran the following command:

mex arrayProduct.c

but there is was an error:

Error using mex

/usr/bin/ld: cannot find -lstdc++

collect2: error: ld returned 1 exit status

could you please give me some help?
