在LabVIEW中数学公式脚本和MATLAB脚本的源代码(Mathematical formulas in LabVIEW, MATLAB scripts and script source code)

图像处理程序集 (Image processing assembly )

说明：  BP算法是应用最广泛的神经网络算法，常用于预测，得到了很好的效果(BP algorithm is the most widely used neural network algorithm, commonly used in forecasting, we get good results)

完整的算术编码的编码和译码程序。结合教材：王育民版的信息论与编码。(Complete arithmetic coding and decoding procedures. The combination of teaching: Wang Yumin s version of the theory of information and coding)

用于计算电力系统的节点阻抗或者导纳，还算比较好用。(It can be used to calculate nodal impedance or admittance of power system.)

用修正的周期图平均法对信号进行谱估计,采用汉宁窗,分段比较(spectral estimation：theory and application)

语音信号处理 时域分析 短时能量 短时平均过零率 短时自相关函数( a=wavread( beifeng.wav ) subplot(6,1,1),plot(a) N=32 for i=2:6 h=linspace(1,1,2.^(i-2)*N)； )

fasica 独立成分分析MATLAB程序(fastica independent component analysis)

说明：  选择“BreastCancer”数据集，使用支持向量机(SVM)对其进行分类。作为对比，第一次对特征集直接进行支持向量机分类，第二次对特征集进行主成分分析法的特征提取后，再对特征提取后的特征集进行支持向量机分类。并且对比和分析了两次分类的结果。(The BreastCancer data set is selected and classified by Support Vector Machine (SVM). For comparison, the first time the feature set is classified directly by support vector machine, the second time the feature set is extracted by principal component analysis, and then the feature set is classified by support vector machine. The results of the two classifications are compared and analyzed.)
