Hi,

I don't come along with the error message:

WaveletTransform::datl : The data lenght is insufficient to do any
decomposition

using

(d34 = SplineFilter[3,4]; newdata = WaveletTransform[data, d34];)

The length of "data" is 900. I can't imagne that this should be too
short...

It is also not working just trying SplineFilter[x,y] with x=3, x=2, x=1.
Just x=0 prevents me from this error message, but this is not what I
want...

By the way: What is the lower limit of the data length to do
decompositions?


Thanks again for any hint

Harald
