matlab主成分分析的几个案例 包括从协方差矩阵或相关系数矩阵出发求解主成分 从样本观测值矩阵出发求解主成分(Principal component analysis matlab several cases, including the covariance matrix or correlation matrix to solve the main ingredient of departure from the starting sample observation matrix solving the main ingredient)

The zip-file contains the following files for visualizing distributions: - distributionPlot.m: main function that allows creating violin plots - histogram.m: generate histograms with ideal bin width given the number of data points and the spread (Freedman-Diaconis rule). Note that for integer-valued data, each integer gets its own bin. - plotSpread.m: plot point clouds with no overlap. Works well for small number of data points, i.e. when there are less than ~20 values per bin.

本书实现了基于Matlab 与Excel 的实验数据自动处理，有助于完成自动化测试(Based on the book to achieve the automatic processing of the experimental data with Excel, Matlab, helps automate the testing)
