fixedGridTransform

Build a transform on another transform’s vertical grid.

Declaration 

 transform = fixedGridTransform(self,referenceTransform,options)

Parameters

  • self InternalModesBasis instance
  • referenceTransform InternalModesTransform whose grid and weights define the fixed grid
  • options.component "F", "G", or "both"
  • options.projectionTolerance leakage tolerance for retained prefix modes
  • options.maxConditionNumber condition-number limit
  • options.nTailCheck number of rejected tail modes checked for leakage
  • options.preserveSize true to keep rejected rows as zeros

Returns

  • transform InternalModesTransform evaluated on the fixed grid

Discussion

This method evaluates the current basis on the reference grid and builds a weighted pseudoinverse there. It is intended for cases where a model fixes the hydrostatic quadrature grid but needs nonzero-\(\kappa\) IGW modes evaluated on that grid.
