c09dbc 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.
c09dbc performs the inverse operation of
c09dac. That is, given sets of
${n}_{c}$ 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
$n$,
c09dbc will reconstruct the data array
${y}_{i}$, for
$\mathit{i}=1,2,\dots ,n$,
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.
None.
