本文在Matlab7．5下面实现了fisherface算法，选用的人脸库是ORL，其中有40 人，每人有10幅不同的人脸图像。本文选取了每人9幅作为训练(1幅作为测 试)，图像大小为112x92。(In this paper, the following Matlab7.5 realized fisherface algorithm, selection of face database is ORL, in which 40 people, each person will have 10 different people face image. This article is selected as a training per nine (one as a test), image size is 112x92.)

说明：  最小生成树的kruskal算法 自己写的 要是再说有重复 我可就怒了(the Kruskal minimum spanning tree algorithm wrote it myself if I say that there is no duplication of anger on)

Newton-Raphson算法是求解非线性方程组和有限元的主要程序，是工程人员的必会的算法(Newton-Raphson algorithm for solving nonlinear equations and the finite element of the main program, the engineering staff of the algorithm will)

说明：  A fast algorithm for level set-like active contours

分析了MATLAB/Simulink 中DSP Builder 模块库在FPGA 设计中优点， 然后结合FSK 信号的产生原理，给出了如何利用DSP Builder 模块库建立FSK 信号发生器模 型，以及对FSK 信号发生器模型进行算法级仿真和生成VHDL 语言的方法，并在modelsim 中对FSK 信号发生器进行RTL 级仿真，最后介绍了在FPGA 芯片中实现FSK 信号发生器的设 计方法。(Analysis of the MATLAB/Simulink in DSP Builder Blockset in the FPGA design advantages, and then combined with the emergence of the principle of FSK signal is given how to use DSP Builder Blockset establish FSK signal generator model, as well as the FSK signal generator model algorithm class VHDL simulation and generation language approach, and in ModelSim for FSK signal generator for RTL-level simulation, and finally introduce the FPGA chip realize FSK signal generator design method.)
