Application of Mixed Programming of VB and MATLAB to CAI System

The mixed programming method of Visual Basic and MATLAB is utilized to develop computer-assisted instruction procedures(CAI),which takes full advantages of Visual Basic′s friendly graphic user-interface and MATLAB′s powerful numerical compute ability.ActiveX DLL and COM components are essential for designing the CAI system,and it is helpful to connect Visual Basic and MATLAB and put them together.At last the CAI of signal and system is practically given to illustrate the application of mixed programming with Visual Basic and MATLAB.
