一个采用Matlab编写的设计FIR滤波器的教程和源代码，便于新手学习设计滤波器和数字信号处理。(a Matlab design prepared by the FIR filter guide and source code, newcomers to facilitate learning how to design filters and digital signal processing.)

Simple Tracker *Tracking* , or particle linking, consist in re-building the trajectories of one or several particles as they move along time. Their position is reported at each frame, but their identity is yet unknown: we do not know what particle in one frame corresponding to a particle in the previous frame. Tracking algorithms aim at providing a solution for this problem. (SIMPLETRACKER a simple particle tracking algorithm that can deal with gaps *Tracking* , or particle linking, consist in re-building the trajectories of one or several particles as they move along time. Their position is reported at each frame, but their identity is yet unknown: we do not know what particle in one frame corresponding to a particle in the previous frame. Tracking algorithms aim at providing a solution for this problem. |simpletracker.m| is- as the name says- a simple implementation of a tracking algorithm, that can deal with gaps. A gap happens when one particle that was detected in one frame is not detected in the subsequent one. If not dealt with, this generates a track break, or a gap, in the frame where the particle disappear, and a false new track in the frame where it re-appear. )

清华大学周东华教授提出的强跟踪滤波器，有效改善突发干扰下的跟踪能力。(Strong tracking filter supposed by Pro. ZHOU Dong-hua, which enhanced the tracking ability during sudden disturb.)

用此程序中您可以控制鼠标并单击或双击您想要的位置，而不必鼠标！这些项目有利于教学软件。这些程序中还用到C库！(With this program you can control mouse and click or double click anywhere you like without touching mouse ! also upload keyboard_simulation for controlling keyboard without touching it ! These programs is good for teaching softwares. In these programs c library is used ! )

this is a matlab program for function
