sparseKePeAxis

Sparse kenetic-potential energy ratio Axis.

---

Declaration

 [kePeAxis,bins_kepe] = sparseKePeAxis(self)

Parameters

• self WVDiagnostics object

Returns

• kePeAxis output value kePeAxis
• bins_kepe output value bins_kepe

Discussion

This function is used by create1DMirrorFluxes to create an efficient ke-pe axis.

The bin assignments, bins_kepe, 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);
