轴系设计计算 分析轴系传动中的最佳参数，并优化设计方案 (Design and calculation of shaft drive shaft of the best parameters, and optimize design)

polydern: partial derivatives of a n-dimensional polynomial model created by polyfitn. usage: pout = polydern(p,diffvar)

特征抽取代码，相关类型一应俱全，实验材料与代码均有(feature extraction)

Matlab中的双馈发电系统模型，包括电机模型和控制部分，可以随意修改电机参数(Matlab DFIG)

基于MATLAB的正交相移键控QPSK编程,根据信号流程编写源程序,并通过时域图表示信号流程(MATLAB based on the Quadrature Phase Shift Keying QPSK programming, signal flow in accordance with the preparation of source code, and through time-domain signal flow graph)

ECG is the graphical recording of the electrical activity of the heart and recognized biological signal used for clinical diagnosis. The ECG signal is very sensitive in nature, and even if small noise mixed with original signal the various characteristics of the signal changes. The signal voltage level is as low as 0.5 to 5mV and is susceptible to artifacts that are larger than it. The frequency components of a human s ECG signal

在轴箭头绘制坐标空间是很困难的，因为Matlab的内置函数图工程箭头坐标空间。这个函数的轴到图坐标计算及放置在正确的位置注释箭头。它还提供了一个按钮式功能重新同步线和箭头如果调整轴或人物，或变更线的属性。(Plotting an arrow in axis coordinate space can be difficult, since Matlab s built-in arrow function works in figure coordinate space. This function does the axis-to-figure coordinate calculation and places an annotation arrow in the correct location. It also provides a button-down function to re-sync the line and arrow if you resize the axis or figure, or change the line properties.)

响应面的2阶多项式估计，使用最小二乘法，算法精度高，data数据随便换其他的三维数据(2-order polynomial response surface is estimated using the least squares method, the algorithm accuracy, data data was replaced with other three-dimensional data)
