Proficient VC and MATLAB joint programming (VI)

Matlab c\c++ function Library is an important part of the extension function of Matlab, contains a lot of MATLAB functions rewritten with c\c++ language, including elementary mathematics function, linear algebra function, matrix operation function, numerical calculation function, special mathematical function, polynomial function, Interpolation functions, users can call these functions in their own c\c++ programs to achieve complex matrix computing functions, thereby reducing the workload of programming, it needs to be explained that C function library and C + + function library is two different function libraries.

Installation is required before use:

In the MATLAB command window, enter:

Mbuild-setup

Follow the prompts to select the VC compiler, completed in the MATLAB command Window input:

Mex-setup

Also select the VC compiler, the compiler to complete the installation and configuration.

Firstly, we introduce the library functions of C function library and C functions library under this directory: Matlab root directory: \extern\lib

Here is a matlab with a use of C function library example (all using the C function example in: Matlab root directory \extern\examples\cmath):* EX1.C
