介绍了matlab中常用的优化函数并给出了算例(Describes the commonly used optimization function matlab)

基于快速傅里叶变换的MATLAB实现，内附有源程序(MATLAB based on fast Fourier transform implementation, enclosing a source)

信号分析与处理中的卷积，适用于合成地震记录(Signal analysis and processing of convolution, for synthetic seismograms)

使用matlab进行有限长fir滤波器设计，要求写出代码画出仿真图形(design fir)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)
