基于Simulink的FIR数字滤波器的设计与实现(Simulink-based FIR digital filter design and implementation)

I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

通过matlab编程 进行GPS单点定位进行测速来反映所测地点晃动情况，采样数据1s（1Hz） loadobsrinex.m 为接收机即所用GPS得到的监测数据，loadrinexGpsn.m GPS星历数据，single_v_main1.m是主程序，还有其他消除误差程序。(Through matlab programming for GPS single point positioning speed to reflect the test place moving situation, and the sampling data 1 s (1 hz) Loadobsrinex. M for monitoring data, used the GPS receiver got loadrinexGpsn. M GPS ephemeris data, single_v_main1. M is the main program, and other procedures to eliminate error. )

code for computing the entropy of gray scale image, including to calculate the local entropy (especially for matlab 7.0 and lower that dont have entropy and entropyfilt function)

说明：  自适应滤波和仿真实验，有毕设的同学可以参考下(Adaptive filtering and simulation experiments, there is complete set up for students to refer to the following)
