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.)

刘维的《精通Matlab与Cpp混合程序设计》。 本书主要介绍如何运用Matlab与C/C++进行混合程序设计。共分8章，主要包括：Matlab程序设计初步、Matlab编译器、Matlab与C语言的接口、生成可独立运行的Matlab程序、Visual C++调用Matlab程序、Matlab DotNet Builder与Visual C++、Matcom与C/C++以及Visual C++调用Mattab C++数学库。另外，附录中介绍有关动态链接库的基础知识。(By Liu Wei. This book describes how to use Matlab and C/C++ mixed programming. Is divided into eight chapters, including: Matlab programming initially, Matlab compiler, Matlab and C language interface, generates an independent run Matlab programs, Visual C++ calling Matlab program, Matlab DotNet Builder and Visual C++, Matcom and C/C++ and Visual C++ call Mattab C++ math library. In addition, the appendix introducing the basics of the dynamic link library.)
