I'd like to know how MATLAB R2012a handles time series which length is not power of two in discrete wavelet transformation (DWT). As I know, in DWT, the sample size N must equal to 2^J (J=decomposition level). But when I load the series with length N=365, and decompose to 5 levels, there were results coming out. So, what is the theory or method used behind?
For your information, I'm using Wavelet Toolbox with graphical interface('wavemenu'), one-dimensional wavelet. Thanks in advance for anyone's help.
