MATLAB在物理中的应用,在学习物理的同时也能掌握一门计算机技术，并能熟练应用计算机技术来学习物理和分析物理。(MATLAB in the application of physics, the study of physics can also master a computer technology, and can skillfully using computer technology to study physics and physics analysis.)

在matlab下利用空间均值法、中值法、最大值法和最小值法实现数字图像的平滑处理(Use of space under the matlab mean, median method, the maximum and minimum method method of smoothing digital images)

利用均匀分布产生高斯白噪声随机数，瑞利随机数，泊松随机数。附有报告~(The use of Gaussian white noise uniformly distributed random number generation, random number Rayleigh, Poisson random number. Accompanied by the report-)

统一设定带宽、脉宽、采样率、脉冲重复频率，用Matab产生16个脉冲的LFM，每个脉冲有4个目标（低速，静止，高速，低速），第3个目标的距离、速度与学号有关。前3个目标的幅度相同，第四个目标幅度是前三个的一半。且距离与第2个静止目标相同。 依次做如下处理： 1 脉压 2 脉压后，相邻2脉冲做MTI（即相邻2个脉冲对应相减），产生15个脉冲 3 脉压后，16个脉冲到齐后，做MTD，输出16个多普勒通道 4 对MTD结果做CFAR（恒虚警） (Unified set bandwidth, pulse width, sampling rate, pulse repetition frequency, and produces 16 pulses Matab LFM, with four goals each pulse (low-speed, static, high-speed, low speed), the first three goals of distance, speed and Student ID related. The first three goals of the same magnitude, and the fourth target range is half of the first three. And from the stationary target with the first two the same. Followed by treatment as follows: 1 pulse 2 pulse pressure, the adjacent two pulses do MTI (that is adjacent to two pulses corresponding to the subtraction), resulting in 15 pulse 3 pulse pressure, 16 pulses in attendance after doing MTD, 16 Doppler channel output 4 MTD results do CFAR (CFAR))

说明：  matlab 中很实用的源代码5：20.形态学骨架提取 25 21.直接提取四个顶点坐标 26 22.文件打开窗口 27(Practical source code of matlab )

这是用matlab编写的分数阶系统仿真程序，希望对你有所帮助。(This using Matlab soft for the fractional system simulink and I hope to help you.)

将最小二乘法应用在目标跟踪，用matlab语言实现的，效果还行。()

Compute log(sum(exp(x),dim)) while avoiding numerical underflow. By default dim = 1 (columns).

image segmentation,very good
