《MATLAB函数速查手册》较全面地介绍了MATLAB的函数，主要包括MATLAB操作基础、矩阵及其基本运算、与数值计算相关的基本函数、符号运算的函数、概率统计函数、绘图与图形处理函数、MATLAB程序设计相关函数、Simulink仿真工具函数、图形用户界面制作函数、信号处理工具箱函数和符号数学工具箱函数等内容。(The MATLAB function Quick Reference " comprehensive MATLAB functions, including the MATLAB operation based matrix and its basic operations, and numerical calculation of the basic function, the function of symbolic computation, a function of probability and statistics, graphics and graphics processing function MATLAB programming function, function of Simulink simulation tools, graphical user interface making function, signal processing toolbox functions and symbolic math toolbox functions and other content.)

律u律pcm编码 若输入A律PCM编码器的正弦信号为x(t)=sin(1600πt),采样序列为x(n)=sin(0.2πn),n=0,1,2,…,10，将其进行PCM编码，求出编码器的输出码组序列y(n)。 要求：1) 直接采用A律扩展器函数求解上述问题。 2）使用13折线法近似A律PCM 求解上述问题。 3）计算量化误差。(Law a law pcm coding If the input A-law PCM encoder is sinusoidal signal x (t) = sin (1600πt), for the sample sequence x (n) = sin (0.2πn), n = 0,1,2, ..., 10, it will be PCM coding to obtain the coded output code group sequence y (n). Requirements: 1) directly A-law expander function to solve the above problems. 2) using a 13 fold line approximation A-law PCM to solve the above problems. 3) calculating the quantization error.)
