这是QAM(正交幅度调制)的MATLAB仿真源程序(This is a QAM (quadrature amplitude modulation) of the MATLAB simulation source)

说明：  MLS代码 实现程序的运行 可用于图像识别(MLS programme)

matrix laboratory的缩写，矩阵实验室的意思。一开始它是一种专门用于矩阵数值计算的软件。自MATLAB4.0版本问世以来，该软件成为最具有吸引力，应用最为广泛的科学计算语言。我们这个课就拿MATLAB6.1版本来讲。（6.x版本大同小异） (At present, the MATLAB software is not only into the businesses, companies and research institutions, but also in institutions of higher learning from college students to doctoral students must master a basic skill is essential computational tools,)

In this report, we devise a methodology for identifying the species of an iris amongst 3 based on 4 distinctive features. We first cover the constitution of the data set and input patterns. We then determine the layout and structure of the neural network we will use for the classification. We continue by testing the network in real life conditions. We conclude with a review of the methods used, and how they could be improved.

转子振动信号的频域分析，可以有效的反映系统的主频和由于故障导致的多倍频(spectrum analysis of rotor vibration signal)

一个介绍如何使用matlab的文献，还详细说明了原理(A paper about the matlab filter and it introduction how to use it.)

计算风险管理中的信用风险溢价的matlab程序(Calculation of risk management in credit risk premium matlab program)

排序学习中经常用到的评价指标为MAP，本程序为该指标的计算函数。(calculate the mean average precision for learning to rank)

在本程序中，轻松实现了阵列信号角度的估计。(In this program easily estimate of the angle of the array signal)
