二阶系统一次性完成的最小二乘法辨识程序，便于理解最小二乘辨识的原理(Completed a one-time second-order system least squares identification procedure, easy to understand the principle of least squares identification)

精细积分法的matlab源代码，请解压后将后缀名改为.m(Precise integration)

simulation of a typical Orthogonal Frequency Division Multiplexing (OFDM) transmission

ofdm.m为主程序，可以运行，将得到迭加噪声之后的误码率曲线，并与理论QPSK加高斯白噪声误码率曲线比较，两者将重合(ofdm.m-based program, you can run, will be after the noise superposition error rate curve, and with the theoretical QPSK plus white Gaussian noise bit error rate curves, which will coincide)

三相桥式全控整流电路 变压器 Yd11 联结(Three-Phase Full-Bridge Controlled Rectifier Transformer Yd11 Connection)

该算法利用BP神经网络描述了一个同心圆的分类算法。特点是可以任意定义多个隐层及隐层内的神经元数目。(the algorithm discribed a category of samecircle.with it you can define any number of buried layer and never cell number of each buried layer.)

用于学习matlab语言编程的PPT文档，里面含有编程源代码。(Matlab programming language for learning PPT document, which contains programming source code.)

Abaqus2Matlab是提取有限元分析程序分析结果。这个工具箱旨在提供一个有限元分析和MATLAB之间的联系,这将使有限元分析用户在MATLAB有限元分析结果进行后处理。它可以用来从一个有限元分析检索结果分析,这可以很容易地从有限元分析转移到MATLAB进行进一步处理。(Abaqus2Matlab is a program for the extraction of ABAQUS analysis results to MATLAB. It is a toolbox which aims to provide a link between ABAQUS and MATLAB, which will enable ABAQUS users to perform postprocessing of ABAQUS results in MATLAB. It can be used to retrieve results an ABAQUS analysis, which can be easily transferred ABAQUS to MATLAB for further processing. )
