利用龙格-库塔法求解了航天器深空返回再入运动动力学方程，并对返回再入运动进行了仿真分析。(Use of Runge- Kutta method to solve the deep-space spacecraft reentry return movement dynamics equations, and the return movement is simulated reentry.)

实现数字信号的QPSK调制，并绘制频谱图(QPSK modulation of digital signal, and map spectrum)

说明：  共轭梯度法是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点(Conjugate gradient method is between the steepest descent method and Newton method between a method that only use the first derivative information, but the steepest descent method to overcome the disadvantage of slow convergence)

多载波调制解调 串并变换 快速傅里叶变换(String of multi-carrier modulation and demodulation and fast Fourier transform transform)

加汉宁窗的低通滤波器，做出干扰信滤波前后的时域图和频谱图(Low-pass filter with Hanning window is used to make time-domain and frequency-spectrum diagrams before and after interference signal filtering.)

说明：  matlab悬浮系统变结构控制 主要是simulink(Variable Structure Control suspension system)

《MATLAB统计分析与应用：40个案例分析》程序与数据第7章 的源代码：方差分析(" MATLAB statistical analysis and application: 40 Case Studies" program and data in Chapter 7 of the source code analysis of variance)

图像处理常见实例的在matlab环境下的具体实现，源码程序，对于初学者不可或缺。(Common examples of image processing in matlab environment, the specific implementation, the source program, for beginners is indispensable.)

学习语音增强一篇很好的博士论文，希望对大家有帮助(Learning a good speech enhancement dissertation, we hope to help)

一个模拟退火算法的例子，程序虽然简单但降温条件，降温函数，内外终止准则都有。可供初学者参考。(Example of a simulated annealing algorithm, the program is simple but cool conditions, cooling function, both inside and outside the termination criterion. Reference for beginners)
