sparsePseudoRadialAxis

Create Sparse Pseudo-Radial Wavenumber Axis and Bin Assignments.

---

Declaration

 [kp,bins_0,bins_pm] = sparsePseudoRadialAxis(self)

Parameters

• self WVDiagnostics object

Returns

• kp output value kp
• bins_0 output value bins_0
• bins_pm output value bins_pm

Discussion

This function is used by create1DMirrorFluxes to create an efficient pseudo-radial wavenumber axis.

The bin assignments, e.g. bins_0 and bins_pm, can be used to create sparse matrices for efficient binning operations.

  valid = ~isnan(bins_0);
  S_0 = sparse(find(valid), bins_0(valid), 1, numel(wvt.Ap), numel(kp), nnz(valid));
  F_wwg_kp_val = reshape(E0(:).' * S_0,[],1);
