MATLAB优化工具箱的应用例子介绍 各种优化工具箱的使用方法(MATLAB Optimization Toolbox application example describes the use of various optimization toolbox)

this is canny edge detector to capture the edge of the imge.it is a good feature descriptor

用matlab编写的基于局部线形化方法的软件可靠性预测方法(using Matlab prepared by the Local Alignment methods of software reliability prediction method)

一维模型的Zoepprit方程正演的matlab程序，还是挺有用的，希望大家下去看看！(Zoepprit equation one-dimensional model of the forward matlab program, or quite useless, I hope you go to see!)

从先验概率中采样，计算权重，可实现对二维数据的聚类，采用偏最小二乘法，仿真效果非常好，随机调制信号下的模拟ppm，是机器学习的例程。( Sampling a priori probability, calculate the weight, Can realize the two-dimensional data clustering, Partial least squares method, Simulation of the effect is very good, Random ppm modulated analog signal under Machine learning routines.)

RNW_perm(A) 利用Ryser-NW方法，计算n*n矩阵A的积和式。计算时间随着n 以2的指数倍增长。计算20*20以内的矩阵很快。 Hperm(A) 利用双元素展开计算非常稀疏的矩阵的积和式 symmRegular(n,k,m) 该命令要调用symmGen函数。 生成对称的k-regular n阶0-1矩阵的启发式算法。 参数n,k是必须的。m的默认值是10。 m设定尝试次数，如果该命令显示 fail ,表明经过m次尝试， 没有生成满足条件的矩阵。 symmGen(n,k) 这里k是一个n维向量，该命令启发式地生成一个以k为行和 的对称0-1矩阵。不能保证每次都成功，不过成功的概率一 般情况下尚可接受。(some useful code for numerical analysis)
