Hi all!
Changing boundary conditions (bc) from "periodic" to "symmetric" in wd (discrete
wavelet transform function) results in increasing of number of wavelet
coefficients. I have a set of 1024 points (i.e. 10 resolution levels), so
instead of 1023 (like in "periodic" case) wavelet coefficients I get 1079.
On the other hand, accessD gives me the right number of coefficient per level,
but the values differ from wd$D (those coefficients are the same in "periodic"
case whether we call wd$D or accessD).
Does anyone have an explanation?
Cheers!
