randomAmplitudesWithSpectrum

initialize with coefficients following a specified spectrum

Declaration 

 Ap,Am,A0] = randomAmplitudesWithSpectrum(options)

Parameters

  • A0Spectrum (optional) function_handle with signature @(k,j), defaults to a white spectrum.
  • ApmSpectrum (optional) function_handle with signature @(k,j), defaults to a white spectrum.
  • shouldOnlyRandomizeOrientations boolean indicating whether randomness in amplitudes should be eliminated (default 0)

Returns

  • Ap matrix of size [Nj Nkl]
  • Am matrix of size [Nj Nkl]
  • A0 matrix of size [Nj Nkl]

Discussion

This allows you to initialize amplitudes following a spectrum defined in terms of wavenumber and vertical mode.
