matlab实现高斯分布

采用小波变换的方法实现心电信号的滤波，分别使用了硬阈值、软阈值和改进阈值方法，并实现了滤波效果的评价（均方差和信噪比）(Wavelet transform of ECG signal filtering method, respectively, using a hard threshold and soft threshold and improve the threshold method, and to achieve the filtering effect of the evaluation (both variance and signal to noise ratio))

说明：  用于支持向量回归（SVR）和启示向量回归（RVR）分析以及交叉验证，以评估预测能力。(It is used for support vector regression (SVR) and Revelation vector regression (RVR) analysis and cross validation to evaluate prediction ability.)

应用背景This document briefly summarises “Version 1” of the SparseBayes software, designed to run within the Matlab environment (see www.mathworks.com). The latest version of this software, along with other explanatory materials, should be available from: http://www.relevancevector.com This documentation refers specifically to Version 1.1 of SparseBayes. Version 1.1 is a baseline re-implementation of the V1.0 package (dating from 2002) that was originally freely downloadable from Microsoft Research1. Please note that SparseBayes is not intended to be a fully comprehensive library or toolbox. Instead, the software comprises a basic set of representative routines implementing the necessary core functionality for “sparse Bayesian” models, such as the “relevance vector machine”. It was originally designed as both a useful demonstration and a base upon which interested users can build more practical code.关键技术A brief description of each file
