Call C from MATLAB
A shared library is a collection of functions dynamically loaded by an application at run time. The MATLAB interface supports libraries containing functions defined in C header files. To call functions in C++ libraries, use the interface described in Call C++ from MATLAB.

C language features not supported.
Rules for using C language structures in a shared library.
Errors occur when the shared library is not a valid library.
This error occurs when you call a function without the correct input or output arguments, or if there is an error in the function signature in the header file.
Some shared libraries, compiled as Microsoft® Windows® 32-bit libraries, use a calling convention that is incompatible with the default MATLAB calling convention.
