[matlab在数学建模中的应用]一书源代码( "Matlab mathematical modeling," a book source code)

说明：  s1 is the M-file description of the SIMULINK system named s1. The block-diagram can be displayed by typing: s1. SYS=s1(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

有一个信号，如果抽样频率，设计一个M点滑动平均系统，要求虑除信号中500Hz的成分，用MATLAB编程仿真结果，确定M的值并画出滑动平均系统的幅频特性图。(Have a signal, if the sampling frequency, to design a M point moving average systems, requirements, in addition to the composition of 500 hz in signal with MATLAB simulation results, determine the value of M and draw the amplitude-frequency characteristics of moving average systems. )

Abstract—Numerous methods have been developed for holistic face recognition with impressive performance. However, few studies have tackled how to recognize an arbitrary patch of a face image. Partial faces frequently appear in unconstrained scenarios, with images captured by surveillance cameras or handheld devices (e.g., mobile phones) in particular.
