Hello all,
I'm using the function rob.dwt of the wavelets
module to get the robust discrete wavelet transform of a non-periodic
signal of length
not divisible by 2^(n.levels), using "polynomial or reflection" as boundary
correction. I get the following error message:
"Problem in left.pad(y, end = lp + p): There are no boundary extensions for
interval wavelets".
The classical dwt function works without problem for my data and with the
same options. The wavelet help says that rob.dwt uses the same options as
dwt, but
it seems that the only boundary corrections available are "periodic" for
dyadic sample sizes and "infinite" with pedg=-1 for samples of any size.
Does anybody know what could be the problem ?
Thanks in advance for you help !
Maria
