把运筹学中的各种算法如线性规划、最小树最短路径的算法用matlab来实现(some matlab program about oprational research,for example LP,min tree e.t.)

字典树的基本功能是用来查询某个单词（前缀）在所有单词中出现次数的一种数据结构，它的插入和查询复杂度都为O(len),Len为单词（前缀）长度，但是它的空间复杂度却非常高，如果字符集是26个字母，那每个节点的度就有26个，典型的以空间换时间结构。(The basic function of the dictionary tree data structure is used to query a number of times a word (prefix) appears in all the words, which insertion and query complexity are O (len), Len is a word (prefix) length, but its space complexity is very high, if the character set is 26 letters, and that the degree of each node will have 26, the typical structure of space for time.)

是CDMA仿真系统产生，很多都讲倒了要仔细查阅的(CDMA is generated simulation system, many say it upside down to the detailed inspection)

该融合工具箱由一系列保存成.m的格式文件函数组成，可对经过配准好的灰度图像进行融合操作。界面操作简单，在界面上可以对相关参数进行设置。(The integration kit is saved into a format function of m, operating after registration good grayscale image fusion. The interface is simple, set the relevant parameters in the interface.)

用matlab实现模式识别里的K-均值聚类算法，算法简单(Pattern Recognition using matlab to achieve in the K-means clustering algorithm, the algorithm is simple)

录制一段自己的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用窗函数法和双线性变换设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Section of their own voice recording signal, and recording the signal sampling draw sample after the speech signal time-domain waveform and frequency spectrum given filter performance indicators, using a window function method and bilinear transformation design of filters, and draw the frequency response filter then use the filter of their own design for the signal acquisition filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes playback voice signal Finally, the design of a signal processing system interface.)
