从EXCEL中读取数据，提供了替换掉不理想数据的方法，还阐述了如何将数据写入EXCEL。(It can read data from EXCEL and provide method of replacing unsatisfactory data, but also explain how to write data to EXCEL.)

捷联惯导仿真程序，可以比较好的帮助理解捷联惯导的原理，主要参考陈哲老师的捷联惯导原理(Strapdown inertial navigation simulation program, can help to understand better the principle of strapdown inertial navigation, strapdown references Chen Zhe teacher inertial navigation principle)

One of the most popular measurements of an ECG signal is the heart rate in this function we describes how to extract the R peak of a signal in order to analyze them in the "Regularity_Rythm" Function. The peak with the highest amplitude is called the R wave. An RR interval is the time that elapses between two successive R waves.

这是关于混沌理论及应用方面的基础资料,希望对大家有帮助,里面含有几个falsh信道模型(This is on the application of chaos theory and the basis of information you would like to help, which contains several falsh channel model)

Intuitive manipulation of a figure using key and mouse gestures(Especially useful for 3d renderings, this widget allows the user to intuitively rotate, pan and zoom any axes within a figure using key presses and mouse gestures. Additionally, press q to quit the widget, r (or double-click) to reset the current axes and escape to close the figure.)
