本书是一本数值线性代数的导论性著作，作者深刻阐述了数值代数的基本思想，加上他们清新、引人入胜的写作风格，使得本书成为本领域的经典之作(This book is an introductory numerical linear algebra book, the author expounded the basic idea of numerical algebra, together with their fresh, engaging writing style makes this book a classic in the field)

数学建模 蚁群算法最短路径通用Matlab程序(Ant Colony Algorithm for shortest path Matlab source code)

录制一段个人自己的语音信号，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。(Record a person s own voice 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 the bilinear transform filter design 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 of voice signal Finally, the design of a signal processing system interface.)

说明：  该程序实现OFDM系统中块状导频的信道估计，块状导频用于时变较慢的多径信道，可以估计出每个载波上的信道传输情况。(The programme realizes channel estimation with block pilots.)

说明：  配电网规划必须满足辐射性和连通性，配电网扩展规划问题随机产生的初始群体中往往存在大量不可行解，采用根节点融合法可确保方案的可行性。(Distribution network planning must meet radiation and connectivity, distribution network expansion planning problem with randomly generated initial population there is often a large number of infeasible solutions, use of root fusion method to ensure feasibility.)

几个简单的空域滤波器程序，包括Guassian、laplace和unsharp(A few simple spatial filter process, including the Guassian, laplace and unsharp)
