可以进行简单的人脸识别，程序简单适合初学者！！(It is a very simple matlab program of face detection.)

温度变化对光纤光栅布拉格波长的影响，通过二维图像表示出。(The impact of temperature change on the optical fiber grating Bragg wavelength is shown through the two-dimensional image.)

algorithm can be easily implemented in matlab

这是计算光子晶体程序，对研究光子晶体的同行很有用(This is the calculation procedures for photonic crystals, photonic crystals to study the usefulness of the peer)

说明：  常微分方程的MATLAB解法教程详解，包含ODE45等经典函数的例子(Detailed tutorials in how to get Solution of Ordinary Differential Equations by MATLAB , includingclassic example of a function ODE45,ode23,etc)

质心探测法，又称为功率加权法，用来寻找峰值点的位置(centroid detection method)

说明：  1、随机生成一个5*5矩阵A，元素符合均匀分布；再随机生成一个5*5矩阵B，元素符合正态分布。对A和B进行加、减、乘、除、比较等矩阵运算，查看运算结果。 2、创建5阶魔术矩阵，求A的行列式、特征值、逆、秩、迹、条件数。 3、假设矩阵 ，求A的LU分解、正交分解、特征值分解、奇异值分解。 4、创建6阶单位稀疏矩阵，并显示其全部元素。 (1, randomly generated a 5* 5 matrix A, elements in line with uniform distribution then randomly generated a 5* 5 matrix B, elements in line with normal distribution. Pairs of A and B to add, subtract, multiply, divide, comparison matrix operations, view the results of operations. 2, create a 5-order magic matrix, find A, determinant, eigenvalues, inverse, rank, trace, the condition number. 3, assuming that matrix, find A, LU decomposition, orthogonal decomposition, eigenvalue decomposition, singular value decomposition. 4, create a six-order unit of sparse matrix, and display all of its elements.)

LDPC码是目前通信中性能最好的纠错编码之上，这是我在Matlab下编写的LDPC基本解码算法，已经通过调试，大家共同学习(LDPC code is the best communication performance on error-correcting code, this is my prepared in Matlab basic LDPC decoding algorithm has been through debugging, U.S. co-learning)

利用人頭轉移函數鍵麗的濾波器,重建環繞音效.可調整音場角度.(The use of the head of the filter transfer function key Korea, reconstruction surround sound. Adjustable sound field angle.)

该程序对矩阵的求逆运算进行了matlab编程，简便，通用，精度高(The application of matrix inversion has carried on the matlab programming, simple, universal, high precision)
