Question 1.1 Sullivan

离散傅里叶变换，即DFT, 注意：FFT在matlab里有现成的函数可以用，它只是DFT快速实现的一种方法而已。(DFT： Discrete Fourier transform. )

转载的MATLAB中工具箱的汇总，非常全面(reproduced in the MATLAB Toolbox summary, a very comprehensive)

：MATLAB 是目前在国际上被广泛接受和使用的科学与工程计算软件。虽 然 Cleve Moler教授开发它的初衷是为了更简单、更快捷地解决矩阵运算，但 MATLAB 现 在的发展已经使其成为一种集数值运算、符号运算、数据可视化、图形界面设计、程序设 计、仿真等多种功能于一体的集成软件。 (MATLAB is now widely accepted and used in the international science and engineering calculation software. Although However, Professor Cleve Moler its original intention was to develop a simpler, more efficient solution to the matrix operation, but now MATLAB Has been making in the development of a set of numerical computation, symbolic computation, data visualization, graphical interface design, program design Meter, simulation and other functions in one integrated software)

matlab实现的图像水平、垂直投影，可用于人脸检测。(failed to translate)

单因变量偏最小二乘回归matlab程序 程序尚不完善，固定提取了3个主成分，没有做寻求最佳主成分个数；没有做交叉有效性检验 (Single dependent variable and partial least squares regression matlab The program is not perfect, the fixed extract 3 principal components, do not seek the best number of principal components do not cross validation test)
