系统的介绍了STK中Astrogator模块的使用情况，并对STK软件进行了一个全面的介绍，是stk学习的一份好资料(STK & Astrogator)

信号与系统软件实验工具箱，本系统包括七个实验，分别是：信号的时域基本运算、连续信号的卷积与连续时间系统的时域分析、离散信号的卷积与离散时间系统的时域分析、信号的频域分析、连续信号的采样与恢复、系统的频域分析、信号的幅度调制与解调。为了加强学生的计算机编程能力和应用能力，所有实验均提供设计性实验内容，让学生参与编程。本系统既可作为教师教学的实验演示，又可作为学生动手实验的实验系统。(Signals and Systems Software experimental toolbox, the system includes seven experiments, namely: basic operations signals in time domain, the convolution of continuous signals and continuous-time system time domain analysis, convolution of discrete signals and discrete-time systems when domain analysis, frequency domain signal analysis, continuous signal sampling and recovery, system frequency domain analysis, signal amplitude modulation and demodulation. In order to strengthen the student s computer programming skills and ability to provide all the experiments were designed experiment content, allowing students to participate in programming. This system can be used as experimental demonstration of teaching, but also as a student hands-on experiments the experimental system.)

algorithm to find stock price wave when using positive return rate as wave condition.For example, find the S&P500 index whole waves, whose change rate is more than 5 from bottom to top.

基于libsvm的支撑向量机的双螺旋线的的二分类问题。(Two classification libsvm support vector machine based on the double helix.)

说明：  基于高斯消去的LDPC编码程序 改程序主要是将一个一般的校验矩阵化成下三角矩阵，再根据后向递推公式直接得到校验比特值(Of LDPC codes based on Gaussian elimination procedure)

龙格库塔算法Runge-Kutta，包括二阶到四阶的MATLAB程序。(Runge-Kutta MATLAB 123456)

介绍了用MATLAB来实现曲线拟合的方法，对进行该方面学习的人很有效(Described curve fitting using MATLAB to implement the method aspects of the conduct of the study were very effective)

说明：  供配电系统的指导书籍，对供配电原件的选择给予指导(Guide books for the distribution system of choice for the distribution of the original guidance)
