说明：  产生LFM信号。生成一个线性调频脉冲 %*Bandwidth——带宽,-表示降调制 %*Pulsewidth——脉宽 %*Samplespeed——采样速率 %Frequncy——中心频率 %Repeatcircle——重复周期 %Delay——延时,-表示超前 %Pulse——行矢量(LFM signal generate. Generate a chirp pulse %*Bandwidth - bandwidth, - denotes down modulation %*Pulsewidth - pulse width %*Samplespeed - sampling rate %Frequncy - center frequency %Repeat cycle %Delay -- delay - indicates lead %Pulse -- line vector)

扩展卡尔曼滤波在跟踪运动轨迹中的应用（matlab程序）(Extended Kalman filter (EKF) simulation demo)

This program places dates on time axis as DATETICK and works with ZOOM and PAN as DATETICKZOOM by Christophe Lauwerys. But, it also shows the full date after zooming or panning by using the ticks and time-axis label. So, if you zoom in down to second, you won t loose "when" you are. The input arguments are equal to those of DATETICK function, but if more than one axis handle is specified, they all will be LINKED! Also, some other options are available, for example, the use of LOCAL LANGUAGE for the months (default), or the use of an specific date format: DD HH:MM SS.FFF for example. Besides, sometimes with DATETICK you don t get optimal results. This program (try to) fix this problem. Just use it after some plot function with days (see DATENUM) in one of his axis (time-axis): t = linspace(0,1) + now x = rand(size(t)) plot(t,x) axis tight tlabel <---- Enjoy it! Bugs reports and suggestions will be very appreciated! (This program places dates on time axis as DATETICK and works with ZOOM and PAN as DATETICKZOOM by Christophe Lauwerys.
