本书包含MATLAB使用和数学知识的丰富层次。编著本书有四个主要目的：（1） 帮助初学者顺利跨入MATLAB大门；（2） 全面、多层次、细致而深入地叙述MATLAB中数值、字符串、胞元、构架、逻辑、函数句柄六种重要数据类型的应用规则、相互配用和编程规范；（3） 由浅入深地阐述MATLAB三种建模、分析、仿真环境——数值计算、符号计算和Simulink环境的特征和使用要领；（4） 以实例讲述MATLAB代表的现代计算能力对传统算法和思维的影响。(Book contains rich levels of using MATLAB and mathematics knowledge. Compiled the book has four main purposes: (1) help beginners MATLAB entered the door smoothly (2) comprehensive, multi-level, meticulous and thorough account Numbers, strings, cell yuan, in the MATLAB framework, logic and function handles six important application rules, with each other and programming of the data type specifications (3) describes the MATLAB distinguished three kinds of modeling, analysis, simulation environment, numerical and symbolic computation and Simulink environment characteristics and use of the essentials (4) with examples about MATLAB on behalf of the modern computing power s influence on the traditional algorithm and thinking. )

一、穆勒矩阵构成 穆勒矩阵是一个4*4的矩阵，完整描述了介质的偏振属性。可通过水平线偏振光H、垂直线偏振光V，45°线偏振光P，右旋圆偏振光R入射，并分别探测水平线偏振光H、垂直线偏振光V，45°线偏振光P，右旋圆偏振光R出射情况下的能量值，即16种偏振态组合下的强度结果，HH/ HV/ HP/ HR，PH/ PV/ PP/ PR，VH/ VV/ VP / VR和RH/ RV/ RP/ RR。进而Mueller矩阵可按照公式（1）计算得到：(First, the Muller matrix The Muller matrix is a 4*4 matrix that completely describes the polarization properties of the medium. The horizontal line, vertical line polarized light polarized light H V, 45 degrees P linearly polarized light, right circularly polarized incident detection and R, respectively, H vertical horizontal line polarized light polarized light V, 45 degrees P linearly polarized light, right circularly polarized light R emitted under the condition of energy intensity results of 16 kinds of polarization combinations HH/ HV/, HP/ HR, PH/ PV/ PP/ PR VH/, VV/ VP and RH/ RV/ RP/ RR / VR. Furthermore, the Mueller matrix can be calculated according to formula (1):)
