Web[C,L] = wavedec(X,N,'wname') returns the wavelet decomposition of the signal X at level N, using 'wname'. wavedec does not enforce a maximum level restriction. Use wmaxlev to ensure the wavelet coefficients are free from boundary effects. If boundary effects are not a concern in your application, a good rule is to set N less than or equal to fix(log2(length(X))). http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/wavelet/wavedec.html WebMar 12, 2024 · 在MATLAB中，可以使用wavedec函数进行小波分解首页在MATLAB中写出对时间序列小波变换利用mallat算法进行分解，将分解后的小波系数进行自适应阈值去噪，将去噪后的小波系数按照自回归和最小二乘支持向量机进行时间序列预测，最后将预测结果按照mallat算法进行 ... the moment i wake up and put on my makeup
