exercise3(FFT)

used to detect colours

The circular convolution, also known as cyclic convolution, of two aperiodic functions (i.e. Schwartz functions) occurs when one of them is convolved in the normal way with a periodic summation of the other function.

说明：  自适应滤波器相关的matlab程序，包含LMS，RLS算法等的实现。由于太大了，所以该资源分为part1和part2两部分。此部分为part2！(matlab codes related to adaptive filters, including LMS and RLS algorithm, etc. the resource is divided to two parts (part1 + part2) cuz it is oversized.)

说明：  升余弦滚降信号及其功率谱。可以通过它实现通信系统中常用的升余弦滚降系统。用处极大哦~(Raised cosine roll-off signal and its power spectrum. Can achieve through its communication systems commonly used raised cosine roll-off system. Oh ~ great usefulness)

说明：  这是数模比赛里面的多雷达多目标数据融合代码，希望对大家有用~~(This is the Multi-radar data fusion multi-target code of Mathematical Model Competition,Hope to be useful~)

说明：  一种简单的A*寻路算法，可在命令行按要求输入相应起点和终点的坐标。适合于初学者(A simple A* algorithm for path planning, which can input the coordinates of the starting point and end point on the command line as required. It is suitable for beginners.)

阵列信号处理领域的基于Lcmv准则的波束形成方法，对初学者有用。(Array signal processing based on the criteria Lcmv beamforming method, useful for beginners.)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)

this code is matlab code that generate fractal shapes.
