License: L2166-2801 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?
