On entry: the dimension of the arrays
ca and
cd as declared in the (sub)program from which
c09daf is called. This must be at least the number,
${n}_{c}$, of approximation coefficients,
${C}_{a}$, and detail coefficients,
${C}_{d}$, of the discrete wavelet transform as returned in
nwc by the call to the initialization routine
c09aaf. Note that
${n}_{c}=n$ for periodic end extension, but this is not the case for other end extension methods which will be available in future releases.
Constraint:
${\mathbf{lenc}}\ge {n}_{c}$, where
${n}_{c}$ is the value returned in
nwc by the call to the initialization routine
c09aaf.
