Plots time and frequency domains of UWB PPM monocycles and doublets.

这是《Numerical Methods with MATLAB: Implementation and Application》一书的配书程序（Matlab）(matlab code for "Numerical Methods with MATLAB: Implementation and Application")

说明：  最经典的Kalman滤波程序，源码少，功能强大，老外作的(The most classic Kalman filtering procedure, source less powerful, foreigners made)

采用四元数算法，来确定飞行器的姿态状况，同时通过PID方法，调节飞行器的飞行姿态。(Quaternion algorithm to determine the status of the aircraft s attitude, but by PID method, adjusting aircraft flight attitude.)

这个函数中比较了等功率分配和注水分配策略下，MIMO信道的信道容量和中断容量(This function calculates ergodic and outage capacity of correlated MIMO channels )

Codigo para calcular lugar geometrico de sistemas lineales

最优信息法，有序样品聚类——最优分割主代码，可用于样品的检验(Optimal information method, ordinal clustering- the optimal partition master code can be used for the inspection of samples)

频率分析程序 检测信号中的多个频率分量(frequency analyse detective more than one frequency)

用radon变换提取图像的不变形特征，将图像转回原有角度，用于后续识别(Radon transform to extract images with no deformation, the image back to the original point of view for subsequent identification)

This will perform contrast streching on input image
