Introduction

Matlab provides C and Fortran interfaces to access their built-in functions. These interfaces are usually used to connect C (or Fortran) and matlab, but we can also use them just as a library such as OpenCV or OpenGL libraries in C.

Installation

Install Matlab. Assume matlab was installed at C:\Program Files\MATLAB\R2007b

Setup MS Visual C++

I write details based on MS Visual Studio 2005. Follow menus of MS Visual C++ window as:

Tools > Options > Projects and Solutions > VC++ directories >

Show Directory for: > Include Files. Now add

C:\Program Files\MATLAB\R2007b\extern\include

Show Directory for: > Library Files. Now add
```
C:\Program Files\MATLAB\R2007b\extern\lib\win32\microsoft
```
Choose appropriate msvcXX directory by finding your MS VC++ version.

Setup MS Visual C++ for each project

Right Click Project > Property >
Configuration Proeperties > Linker > Input > Additional Dependencies. Now add
- libdflapack.lib libmat.lib libmwservices.lib libeng.lib libmex.lib libmx.lib libfixedpoint.lib libmwlapack.lib libut.lib mclcom.lib mclcommain.lib mclmcr.lib mclmcrrt.lib mclxlmain.lib
Change 'Configuration' drop down menu from Release (Debug) to Debug (Release).
Do the same thing (Add .libs to Input)

Or, add below codes into your source codes above #include(s).

#ifdef _MSC_VER
#pragma comment(lib, "libdfblas.lib")
#pragma comment(lib, "libdflapack.lib")
#pragma comment(lib, "libemlrt.lib")
#pragma comment(lib, "libeng.lib")
#pragma comment(lib, "libfixedpoint.lib")
#pragma comment(lib, "libmat.lib")
#pragma comment(lib, "libmex.lib")
#pragma comment(lib, "libmwblas.lib")
#pragma comment(lib, "libmwlapack.lib")
#pragma comment(lib, "libmwmathutil.lib")
#pragma comment(lib, "libmwservices.lib")
#pragma comment(lib, "libmx.lib")
#pragma comment(lib, "libut.lib")
#pragma comment(lib, "mclcom.lib")
#pragma comment(lib, "mclcommain.lib")
#pragma comment(lib, "mclmcr.lib")
#pragma comment(lib, "mclmcrrt.lib")
#pragma comment(lib, "mclxlmain.lib")
#endif

Typically,

#ifdef _MSC_VER
#pragma comment(lib, "libmat.lib")
#pragma comment(lib, "libmx.lib")
#endif

are enough to use matlab C Library. Add

#pragma comment(lib, "libmex.lib")

if you are supposed to create mex (creation of matlab functions in C). Add

#pragma comment(lib, "libeng.lib")

if you are supposed to use matlab engine (Run matlab process in background to make matlab do computation and receive results seamlessly). Add

#pragma comment(lib, "mclmcr.lib")

if you are supposed to use compiled matlab file in C.

Header Files

#include "matrix.h"
#include "mat.h"

Mex

#include "mex.h"

Matlab engine

#include "engine.h"

Matlab compiler

#include "mclmcr.h"
