用vb实现快速傅立叶变换，运行速度达到最优化，可以c代码媲美，因此可以实现实时傅立叶变换。实现模块化，直接作为一个模块调用即可，非常方便！-with vb fast Fourier transform, speed of operation to achieve the most optimized code can be comparable to c, it can achieve real-time Fourier transform. To achieve modular, as a d

c++的一个很典型的应用就是dll的调用，对于怎么样好的调用dll程序，阅读本程序对您将大有益处。-c of a typical application is dll call, like how good call dll procedures, the procedures for reading you will greatly benefit.

在VB环境中调用MATLAB函数，实现两种环境的交互。这样可以充分利用VB的界面制作功能和MATLAB的矩阵运算能力。 -In the VB environment MATLAB call function, the realization of two interactive environment. This can take full advantage of VB interface produced MATLAB matrix functions and computing pow
