求桁架应力以及支座反力，求各点的位移大小(Truss stress and seek support reaction, seek points of displacement size)

光放大器仿真能够计算出放大的信号功率以及噪声功率(optical amplifier)

信号处理源程序，振动、模态分析经常用的算法，省去每次编写(Source signal processing, vibration, modal analysis method often used, eliminating the preparation time)

it is a matlab file.it is used to do some basic rd in matlab.

矩形脉冲信号CW组合波形的模糊函数图的仿真(Rectangular pulse signal ambiguity function diagram of the the CW combination of waveform simulation)

解决了三维数据可视化的问题；在三维网格点上数据绘制显示它的大小。 通过z轴坐标点更容易区分边缘颜色变化。可以通过设置线宽参数该选项设置为0。(This function solves the problem of visualization of 3 dimensional data in one plot(plot3). Data is plotted on a 3 dimensional mesh with point size showing value of it. Edge color changes via z axis to distinguish coordinate of points easier. That option can be turned off by setting the linewidth parameter to 0. )

说明：  matlab环境下的iris 和 sonar的数据聚类。包括GA、k-means、FCM（只有iris）。(Iris and sonar data clustering in Matlab environment. It includes GA, K-means and FCM(only for iris).)

PATTERN RECOGNITION OF SIMPLE SHAPES IN A MATLAB/SIMULINK ENVIRONMENT

ARIMA建模，主要包括平稳化、模式识别、模型定阶几个步骤(ARIMA modeling, including smoothing, pattern recognition, model order several steps)

4步标定法，主要是实现计算机数字图像处理摄像机的标定，操作简单，比较实用(4-step calibration method is to achieve a computer digital image processing camera calibration, easy operation, more practical)
