求解抛物型方程的交替隐方向P-R差分格式的matlab程序实现。不过大家在用的时候要用到原函数f.m和精确解函数uexact.m，应用程序的时候只要修改精确解和右端项就可以了。(Solving Parabolic Equations PR alternating direction implicit difference scheme of matlab program. But we can use the time to use the original function fm and the exact solution function uexact.m, whenever an application to amend the exact solution and the right side of it.)

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))

基于Matlab 平台根据反馈数字逻辑给出了m 序列的计算机生成源程序和m 序列的基本性质的考察代码。可根据输入的八进制 本原多项式系数生成相应的m 序列。上机结果验证了程序的正确性和有效性(Matlab-based platform based on feedback digital logic m-sequence are given computer-generated source code and the basic properties of m-sequence code visits. According to the octal input primitive polynomial coefficients generate the m-sequence. The machine results validate the correctness and effectiveness of the program)
