信号的反褶、移位、尺度变换.李杰.信号处理MATLAB实验教程.P39(Signal processing)

说明：  这是MATLAB教程中的经典之作，对重要的知识点做了归纳和汇总，讲解也很详细(MATLAB tutorial is classic, the knowledge of important points are summarized and the summary made to explain the very detailed)

3D DCT function in wavelet

菲涅尔衍射的卷积形式以及傅里叶变换形式，可以用matlab模拟出衍射斑(Fresnel diffraction convolution of the form as well as the form of the Fourier transform, can simulate the diffraction spots with matlab)

说明：  QC-LDPC基矩阵H的构建方法及MATLAB实现，具有详细解释(Various encoding and decoding methods of LDPC)

this mdl explains the working of the linear hold circuit

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )

科学计算与MATLAB语言,很不错的介绍matlab的书籍(Scientific Computing with MATLAB language, a very good introduction matlab books)

提出了一种新的基于图像分块重构和线性判别分析相融合的方法，主要用于人脸识别。该方法通过计算两幅图像之间图 像块的重构均值误差，运用线性判别分析求出两幅图像降维后的欧式距离，融合重构误差和欧式距离计算这两幅图像之间的差别 程度。(A new block-based image reconstruction and the integration of linear discriminant analysis method is mainly used for face recognition. This method between the two images by calculating the reconstructed image block average error, calculated using the linear discriminant analysis after dimension reduction of two images Euclidean distance, the integration calculation of reconstruction error and the Euclidean distance difference between these two images level.)

说明：  用Matlab实现蒙特卡罗模拟的源程序,非常的好用(Monte Carlo simulation using Matlab realization of the source program, very easy to use)
