Simplex algorithm method

关于db4小波数据处理的一个简单matlab程序，可供大家参考参考(simple matlab test of xiaobo,it is expected hopleful)

The alogrithm employed in this toolbox for determining Lyapunov exponents is according to the algorithms proposed in [1] A. Wolf, J. B. Swift, H. L. Swinney, and J. A. Vastano "Determining Lyapunov Exponents from a Time Series," Physica D, Vol. 16, pp. 285-317, 1985. [2] J. P. Eckmann and D. Ruelle, "Ergodic Theory of Chaos and Strange Attractors," Rev. Mod. Phys., Vol. 57, pp. 617-656, 1 The algorithm given in [1] is used for first-order systems while the QR-based algorithm proposed in [2] is applied for higher order systems. by Steve W. K.

设计一个matlab雷达信号仿真界面程序。（提示：例如可以根据选择产生一个不同类型噪声（均匀分布、高斯分布等类型），并在界面中显示该噪声时域图形，并能根据要求画出该噪声的自相关、FFT等信号处理后的结果。）(Design a matlab radar simulation interface program. (Hint: for example, can choose to generate a different type of noise (uniform distribution, Gaussian distribution type), and the noise in the interface displays the time domain graph, and can draw upon request of the noise autocorrelation, FFT and other signal processing the results.))

简单实用的基于偶排列的多相滤波吗matlab代码(Simple and practical, based on the even of a polyphase filter matlab code)

一些Optisystem软件的仿真例子，通过这些例子学习可以轻松上手，适合从事光纤研究人员。(some examples for Optisystem)

这是用MATLAB实现的有限数字滤波器设计，与发的滤波器设计一起学，效果会更好(This is achieved using MATLAB limited digital filter design, the filter design and development with science, the effect will be even better)

包括四个.m文件，采用16QAM调制，添加循环前缀与后缀，加窗处理，防震性能很好。(Including four. M files using 16QAM modulation, add cyclic prefix and suffix, window treatment.)

这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法，它在最优化方法中占有重要地位.最速下降法的优点是工作量小，存储变量较少,初始点要求不高；缺点是收敛慢，最速下降法适用于寻优过程的前期迭代或作为间插步骤，当接近极值点时，宜选用别种收敛快的算法. (Matlab implementation of this procedure steepest descent algorithm.)
