computes the inverse one-dimensional maximal overlap discrete wavelet transform (MODWT) at a single level. The initialization function c09aac
must be called first to set up the MODWT options.
performs the inverse operation of c09dac
. That is, given sets of
approximation coefficients and detail coefficients, computed by c09dac
using a MODWT as set up by the initialization function c09aac
, on a real data array of length
will reconstruct the data array
from which the coefficients were derived.
The accuracy of the wavelet transform depends only on the floating-point operations used in the convolution and downsampling and should thus be close to machine precision.
