Matlab在概率统计中的应用 摘 要 Matlab是当今最优秀的科技应用软件之一，它以强大的科学计算与可视化功能、简单易用，特别是附带的工具箱，使得它在世界范围内很是流行，特别是在工程计算领域。近年来越来越多的国人也喜爱上了这一套软件。概率统计是信息处理、科学决策的重要理论与方法，其内容丰富，逻辑严谨，实践性强，应用广泛，是现代管理、科研和工程技术人员必备的基础知识，随着计算机的普及和Matlab软件的发展，概率统计日益走进人们的日常工作和生活。本文主要是讲Matlab在概率统计中的应用，结合概率统计概念、理论和应用，系统的介绍了概率分布、期望和方差、参数估计等问题。本文重点是应用Matlab统计工具箱介绍概率与统计的各种概念、理论、方法、算法及其实现和解决参数估计问题。 关键词：Matlab，概率论，数理统计，概率，方差，数学期望，参数估计 Matlab in probability and statistics application Abstract: Matlab is the most outstanding application of technology, it is a strong scientific computing and visualization features, easy to use, especially with the kit, so it was very popular worldwide, especially in the engineering calculations areas. In recent years more and more people are in love with this set of software. Probability and Statistics is information processing, an important scientific theories and methods of decision-making, and its rich content, logically coherent, practical, widely used, modern management, research and engineering and technical personnel necessary basic knowledge, with the proliferation of computers and Matlab software development, the increasing probability and statistics into peoples daily work and life. This article is about Matlab application in probability and statistics, combined with the concept of probability and statistics, theory and application, the system introduces the probability distribution, expectation and variance, parameter estimation problems. This article focuses on is the application of Matlab statistics toolbox describes the probabilistic and statistical concepts, theories, methods, algorithms and its implementation and to solve parameter estimation problems. Keywords: Matlab, probability theory, and mathematical statistics, probability, variance, mathematical expectation, parameter estimation 目 录 引 言┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄1 Matlab的发展史及其应用┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄1 Matlab在概率统计中的应用基础┄┄┄┄┄┄┄┄┄┄┄┄1 （一）概率密度函数值┄┄┄┄┄┄┄┄┄┄
