c09cbc computes the inverse one-dimensional discrete wavelet transform (DWT) at a single level. The initialization function
c09aac must be called first to set up the DWT options.
c09cbc performs the inverse operation of
c09cac. That is, given sets of
${n}_{c}$ approximation coefficients and detail coefficients, computed by
c09cac using a DWT as set up by the initialization function
c09aac, on a real data array of length
$n$,
c09cbc will reconstruct the data array
${y}_{i}$, for
$\mathit{i}=1,2,\dots ,n$,
from which the coefficients were derived.
None.
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.
