249 is passed the number of vectors in the submap bundle and a vector of
250 flags indicating if any of the vectors are not to be decoded. If the

253 'do not decode' vectors are allocated and zeroed.

288 1) allocate and zero all vectors that will be returned.
421 Format 2 handles 'do not decode' vectors differently than residue 0 or
422 1; if all vectors are marked 'do not decode', no decode occurrs.
423 However, if at least one vector is to be decoded, all the vectors are
426 channel. After decode, deinterleave the vector into independent vectors, one for each output channel. That is:
429 \item If all vectors 0 through \emph{ch}-1 are marked 'do not decode', allocate and clear a single vector \varname{[v]}of length \emph{ch*n} and skip step 2 below; proceed directly to the post-decode step.
430 \item Rather than performing format 1 decode to produce \emph{ch} vectors of length \emph{n} each, call format 1 decode to produce a single vector \varname{[v]} of length \emph{ch*n}.
431 \item Post decode: Deinterleave the single vector \varname{[v]} returned by format 1 decode as described above into \emph{ch} independent vectors, one for each outputchannel, according to:
