本书基于MATLAB 5.2版，提供了使用MATLAB的实践性指导。
MATLAB已成为适合多学科、多种工作平台的功能强大、界面友好
、语言自然并且开放性强的大型优秀应用软件，同时也已成为
国内外高等院校高等数学、数值分析、数字信号处理、自动控制
理论以及工程应用等课程的基本教学工具。本书按逻辑编排，
自始至终用实例描述；内容完整且每章相对独立；
是一本简明的MATLAB参考书，既适用于初学者，也适用于高级
MATLAB用户。对MATLAB与FORTRAN、C等语言结合的描述更是所
有MATLAB书籍中少有的一大特色。 本书适合作为理工科高等院
校研究生、本科生教学用书，也可作为广大科研工程技术人员的
自学用书。(book based on MATLAB version 5.2, providing for the use of MATLAB practical guidance. MATLAB has become suitable for multidisciplinary, multi-platform work of the powerful and friendly interface, natural language and the open-large outstanding software application, but also domestic and foreign institutions of higher learning has become a Higher Mathematics, Numerical analysis, digital signal processing, automatic control theory and engineering applications of the basic curriculum teaching tool. By the logic of the book presentation, from beginning to end, with examples description; As complete and relatively independent of each chapter; is a concise reference book MATLAB, applies to both beginners, and it also applies to senior MATLAB users.

DFT进行频谱分析时的三种现象
1、混叠：对连续信号采样，要求连续信号是带限的，采样频率要足够高。Fs应满足Nyquist采样定理才不产生混叠。
采样前加低通滤波器防混叠
2、频谱泄漏：DFT对时域信号进行了截断（相当于采样信号乘了一个窗函数），时域的乘积相当于频域卷积，改变了原信号频谱。
改用其他窗函数（非矩形）改善泄漏。
3、栅栏现象：DFT 只给出了频谱在采样点上的取值，采样点间的频谱内容丢失。(DFT spectrum analysis of a three phenomena, aliasing : continuous signal sampling, requiring continuous signal is band-limited, the sampling frequency should be high enough. Fs meet the Nyquist Sampling Theorem would not have aliasing. Sampling former low-pass filter plus anti-aliasing 2, spectrum leakage : DFT right time domain signal a disconnect (equivalent to a sampling signal by a window function). time domain is equivalent to the product of frequency-domain convolution, changes in the spectrum of the original signal. Window functions to switch to other (non-rectangular) to improve leakage. 3, fenced phenomenon : DFT spectrum is given only at the sampling point value, sampling points of the spectrum as lost.)
