otsu算法的实现，自适应最佳阈值图像分割方法，最大类间方差算法(otsu algorithm, adaptive optimal threshold image segmentation method, Otsu Algorithm)

DFBREC_L Directional Filterbank Reconstruction using Ladder Structure x = dfbrec_l(y, fname) Input: y: subband images in a cell vector of length 2^n f: filter in the ladder network structure, can be a string naming a standard filter (see LDFILTER)

投影寻踪算法————可以用于多指标的分类等等，是一种比较常用的算法(Projection pursuit algorithm---- can be used for multi-index classification, etc., is a commonly used algorithm)

this file is simulink of DC motor and PID controller

九宫格源代码，用matlab编写的程序比较简单，运行时输入B=shudu2（A），A就是需要填写的九宫格。(Squared source code, using matlab procedure is relatively simple, run-time input B = shudu2 (A), A is a need to fill squares.)

Convolution Encoder and Decoder 1/2 , Viterbi algorithm

说明：  PID控制算法的经典实例哦！希望对大家有用(Documents and Settings)
