MATLAB Wavelet Transform wavdec Returns Matrix of Wrong Size
Hello guys I need help with a question I have regarding the wavdec
anddwtfunctions in MATLAB. I am using wavdec(y,3,db4) on a size 1024
signal, which means I am trying to compute the third level db4 transform
of the size 1024 signal y. If I am thinking about this correctly,
theoretically the returned matrix after the transform should also be of
size 1024. However, when I perform the transform the matrix I get returned
is size 1044, which is 20 samples bigger than my original matrix. Would
anyone please be able to explain to me why this is happening? Thank you!
