Laplace2D

说明：  利用Fisher线性判别来进行男女分类（里面已经有了男女的数据）(Using Fisher linear discriminant for classification of men and women (which already have the data for men and women))

这个是对16QAM各种界的一个整理，给出了仿真程序，对于初学者来说具有重要的意义。(This is a finishing 16QAM various circles, the simulation program, for beginners is of great significance.)

该文档详细描述了FFT的物理意义，并附有一个正弦波叠加的例子和相关Matlab程序.(The document describes the physical meaning of FFT in details,with a superimposed sine wave and related Matlab examples )

深入浅出matlab 7.x混合编程，一本非常详细的介绍matlab7.x与VC之间通过各种方式混合编程的实现方法(Layman matlab 7.x mixed programming, a very detailed introduction matlab7.x and VC mixed programming through a variety of ways to achieve method)

说明：  基于PID控制的永磁同步直线电机速度控制系统，输出速度能够较好的跟踪输入信号，控制效果比较理想(The speed control system of permanent magnet synchronous linear motor based on PID control can track the input signal better, and the control effect is ideal.)

说明：  Function files in MATLAB for calculation of laminate engineering constants for a multidirectional laminate consisting of plies with known values of material data in the principal material directions, known fiber orientations and known ply coordinates.

次程序为PID程序,可以认真学习后得出想要的结果(It s PID program.)

能够很准确的计算单输入单输出系统的信噪比。(Very accurate calculation of the SNR of the single-input single-output system.)
