Calculation-of-Matlab-power-spectrum

这是数字信号处理方面的一些源码，主要涉及信号处理的基本内容，如傅立叶变换，基本的滤波器等。只供学习参考。(This is the digital signal processing some of the source, mainly involving the basic elements of signal processing, such as Fourier transform, the basic filter. Reference for learning.)

Myplotyy情节不同的数据集具有共同的X轴使用一个数字，但个别的Y轴。 每一个曲线（Y轴）的属性可单独调整，为线性或对数尺度，正常或反向规模，置信区间等，颜色，曲线标签，... 见截图和运行示例“myplotyy_example.m”在zip文件中。 (Myplotyy plots different data sets with a common x-axis but using individual y-axes in one figure. The properties of every curve (y-axis) can be individually adjusted, such as linear or logarithmic scale, normal or reverse scale, confidence intervals, colors, curve labeling, ... See screenshot and run the example "myplotyy_example.m" included in the zip-file. )

有关有限元的基本理论与matlab的编程，是浙大徐荣桥老师编写的研究生教材。(For the basic theory and finite element matlab programming, Xu Rong bridge is Zhejiang University graduate teacher preparation materials.)

此matab函数文件可以用来计算模型的李雅普诺夫指数，用于稳定性分析。(this Lyapunov.m file can be used to compute the lyapunov exponential)

说明：  用于提取信号的时频域特征参数，比如信号均值、方差、以及一些无量纲的时域特征参数(Time-frequency domain characteristic parameters used to extract signals, such as signal mean, variance, and some dimensionless time domain characteristic parameters)

说明：  逆冗余曲波变换,或者是逆冗余三角波变换，脊波变换(IRCT.m- Inverse Redundant Curvelet Transform.Its enough.no more to say)

文件包含现代控制理论中的一些控制程序，可供初期学习者使用，这些都是matlab中所没有的程序。(File contains a number of modern control theory control procedures for early learners, these are programs that are not in matlab.)

三个基于延时的波束形成程序，在声纳、雷达等领域有广泛应用，能正常运行，都有仿真图，推荐下载(Three delay-based beamforming codes,have wide applied in sonar, radar and other areas,all of them have the simulation graph, it is recommended to download)

计算一维和二维表面粗糙度Ra，根据需要自行选择。(Calculate one and two dimensional surface roughness Ra, according to the needs of your choice.)
