这是里面是岗萨雷斯（matlab）的第三章代码。(Fernando Gonzalez (matlab))

这是我在学校的一个matlab作业，是编写一个GUI界面，实现打开图像，绘制灰度直方图，进行边缘检测等功能。(This is my school a matlab job is to write a GUI interface to achieve open the image, draw histogram, edge detection and other functions.)

关于调制信号的分形维数的算法，该函数用来计算ASK信号分形信息维数，可以以此类推到其他的调制信号(Fractal Dimension Algorithm modulated signal, the function used to calculate the ASK signal fractal information dimension, can so to other modulation signal)

通过仿真实现同步电机模型，在MATLAB环境下实现(Achieve synchronous motor model by simulation in MATLAB environment to achieve)

说明：  SURROGATES工具箱是一个多维函数逼近和优化方法的通用MATLAB库。当前版本包括以下功能： 实验设计：中心复合设计，全因子设计，拉丁超立方体设计，D-optimal和maxmin设计。 代理：克里金法，多项式响应面，径向基神经网络和支持向量回归。 错误和交叉验证的分析：留一法和k折交叉验证，以及经典的错误分析（确定系数，标准误差;均方根误差等;）。 基于代理的优化：高效的全局优化（EGO）算法。 其他能力：通过安全裕度进行全局敏感性分析和保守替代。(SURROGATES Toolbox is a general-purpose MATLAB library of multidimensional function approximation and optimization methods. The current version includes the following capabilities: Design of experiments: central composite design, full factorial design, Latin hypercube design, D-optimal and maxmin designs. Surrogates: kriging, polynomial response surface, radial basis neural network, and support vector regression. Analysis of error and cross validation: leave-one-out and k-fold cross-validation, and classical error analysis (coefficient of determination, standard error; root mean square error; and others). Surrogate-based optimization: efficient global optimization (EGO) algorithm. Other capabilities: global sensitivity analysis and conservative surrogates via safety margin.)

Given an output function f(x) and a cost function J(x) (and gradients), optimal inverse functions are found which produce the input x* with the lowest cost based on the current desired output. Output and cost functions produce a scalar. The method is demonstrated on 2D problems (for convenient visualization). With 2D plots removed (all but Figure 41), the code can run higher dimension systems also.

说明：  遗传算法，MATLAB例程，交叉适应繁殖变异，结构清晰(Genetic algorithm, MATLAB routine, cross-breeding to adapt to variations in the structure of clear)
