expandedLegacyMappings

Materialize the vertically expanded legacy full-storage mappings.

Developer documentation: this item describes internal implementation details.

Declaration 

 [dftPrimaryIndex,dftConjugateIndex,wvConjugateIndex] = expandedLegacyMappings(nBatch)

Parameters

  • nBatch positive batch count used to expand row indices

Returns

  • dftPrimaryIndex vertically expanded direct Fourier indices
  • dftConjugateIndex vertically expanded Hermitian destination indices
  • wvConjugateIndex vertically expanded WV source indices

Discussion

This temporary compatibility method exists only until issue #71 removes consumers of the old Nz-replicated geometry properties. It is unavailable when conjugated extraction is needed.
