Fisher

说明：  文件里是MATLAB语言常用算法程序集，包括插值、函数逼近、数值微分、数值积分、线性方程组的求解等程序(File is a MATLAB algorithm for the assembly language used, including interpolation, function approximation, numerical differentiation, numerical integration, linear equations and other procedures)

自述的matlab编程小技巧，供代码编写者参考(matlab coding skills)

这个程序可以产生单频简单脉冲序列，LFM脉冲序列，以及单频二相码序列(This simple procedure can produce single-frequency pulse sequence, LFM pulse sequences, and single-frequency two-phase code sequence)

用于MATLAB学习的基础教程，讲解十分详细，内容丰富，介绍了MATLA的安装，使用方法(failed to translate)

matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

非常不错的非线性非高斯环境下的粒子滤波程序进化算法(very good non-linear environment Gaussian filter particles procedures evolutionary algorithm)

manual segmention in matlab

1. 608组样本，第一列数字是标号，第二列数字是出现损坏的时间，第三列表示数据有效性，为0有效 2. 损坏时间是对数正态分布的，需要拟合 3. 求均值80%置信区间 4. 成本为m，价格为s，保证盈利20%，选取保修期 5. 比较保修期和拟合数据的均值 6. 若保修期就是拟合损坏时间的均值，求出利润率 loadd.m：加载样本数据，并选取有效数据 period.m：加载成本、价格数据，计算利润和保修期的关系(1.608 groups of samples, the first number is the label, the second column number is the time to appear damage, the third list shows the validity of the data, which is 0 effective. 2. damage times are logarithmic normal distribution and need to be fitted 3. mean in 80% confidence interval 4. the cost is m, the price is s, the profit is 20%, the warranty period is selected. 5. compare the mean value of the warranty period and the fitting data 6. if the warranty period is to fit the mean damage time, the profit rate is calculated. Loadd.m: load the sample data and select the valid data Period.m: loading cost, price data, and calculating the relationship between profit and warranty period)

本源代码主要实现谐波小波的分解及重构的matlab程序。(Source code of the main harmonic wavelet decomposition and reconstruction of the matlab program.)

matlab调用ansys的例子，适合初学者。(matlab call ansys example, suitable for beginners.)
