Linking MATLAB with Visual C++ or Visual Basic
|
| CEMLinker is the software library that can be used in developing science and engineering applications by MATLAB functionality. Calling MATLAB internal functions or including user-defined M-files in Visual C++/Visual Basic, the developers can easily configure the algorithm such as control; signal processing, communication, vibration and system modeling. CEMLinker provides the easy connection between MATLAB and your application program. |

|
When you configure the application program for the control system analysis using Visual C++ or Visual Basic. CEMLinker provides easy connection between MATLAB and your program. The steps of application example are as follows;
|
| (1) Add library file in Visual C++ or Visual Basic project configuration window as follows. |
|
| (2) Edit your application program and use CEMLinker functions to analyze control systems using bode plot, and step response. |
|
| (3) You can use all MATLAB functionalities such as graph plot (2-D, 3-D, subplot), multimedia input/output (sound, image, video), and hardware connections (real-time DSP board simulation). Using these capabilities, you can optimize your program and decrease code-length and development time.
