Solve non-stiff differential equations

是一本英文版的关于matlab在金融领域应用的书籍，对于需要分析统计海量数据的人有一定帮助哦(This text describes a set of MATLAB functions that implement a host of econometric estimation methods. )

矩阵转换四元数代码 欧拉角转换四元数代码 四元数转换到矩阵代码(The quaternion matrix transformation code Euler angles conversion quaternion code converts quaternion to a matrix code)

Support vector machine is a machine learning method that is widely used for data analyzing and pattern recognizing. The algorithm was invented by Vladimir Vapnik and the current standard incarnation was proposed by Corinna Cortes and Vladimir Vapnik. This application note is to helping understand the concept of support vector machine and how to build a simple support vector machine using Matlab

说明：  matlab线性判别分析函数，首先需要用PCA进行数据压缩，然后提前特征变量，进行判别分析(Matlab for LDA)

只是一个学习的开始，那面有不足之处，gm11的小程序(Just one study that surface inadequacies the gm11 the applet)

用matlab实现算数编码、哈弗曼编码以及LZW编码（能够区分大小写和数字进行编码）含测试文本和结果(Using matlab realize arithmetic coding, Huffman coding and LZW coding (case-sensitive and numbers can be encoded) containing test text and results)

说明：  一个模糊神经网络解耦的MATLAB程序，希望对大家有帮助(A fuzzy neural network decoupling of the MATLAB program, we want to help)

计算Fuzzy Mutual Information and Fuzzy Entropy(calculate Fuzzy Mutual Information and Fuzzy Entropy)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
