nativeTransform

Build a transform on the basis’ native vertical grid.

Declaration 

 transform = nativeTransform(self,options)

Parameters

  • self InternalModesBasis instance
  • options.component "F", "G", or "both"
  • options.nModes maximum number of modes retained
  • options.projectionMethod "auto", "directInverse", "weightedPseudoinverse", or "canonical"
  • options.allowNoncanonical true to allow numerical wave-F projections
  • options.maxConditionNumber condition-number limit for direct inverses

Returns

  • transform InternalModesTransform on the native grid

Discussion

The native transform maps between modal coefficients and fields sampled at basis.z. With projectionMethod="auto", a square, well-conditioned inverse matrix uses a direct inverse; otherwise the transform uses a weighted pseudoinverse.
