拟合椭圆的matlab代码，对给出的至少5个点的数据进行最小二乘拟合。(Elliptical fitting matlab code, at least for the given five-point least-squares fitting of data.)

说明：  本文档中的源代码是利用谱减法对语音信号进行增强，再matlab中运行可达到预期的效果。(The source code in this document is to use spectral subtraction to enhance the speech signal, and then run matlab can achieve the desired results.)

说明：  S变换的源程序,具有很好的时频解析功能，处理非平稳信号的有力武器(S transform source code, a powerful weapon to have good time-frequency analysis, processing non-stationary signals)

This is a matlab code of MTE protocol that simulates the life of the sensor network.

实现串级控制，主要用工业过程控制。是一个仿真程序(Realize cascade control, the main industrial process control. Is a simulation program)

扩展卡尔曼滤波程序，用一个简单的示例进行仿真。对理解卡尔曼滤波有很大帮助。(Extended kalman filtering program, with a simple example of simulation. This example is a great of helping to understand the kalman filter.)

车辆动力学模型，可以用来作动力性能仿真，或是添加其他部件，做复杂模型，该模型已调试通过。(Vehicle dynamics model that can be used for dynamic performance simulation, or add other components, do complex model, which has been through debugging.)

to find correlation coefficient between encrypted and original image

PSO聚类算法使用的数据是我们归一化后的数据，利用该数据求总的粒子数m,设置聚类数c（c=4,这个可以确定的），随机选择聚类中心并赋值给各个粒子，随机产生粒子的速度；(PSO clustering algorithm using data owned by a data after the data requirements to the total number of particles in m, set the number of clusters c (c = 4, this can be determined), the random selection of cluster centers and assigned to the each particle velocity of the particles, randomly generated )
