crossSpectrumWithFgTransform
Compute a real modal cross-spectrum using the F-basis transform.
Declaration
spectrum = crossSpectrumWithFgTransform(firstField,secondField)
Parameters
firstFieldfirst F-space field with shape[Nx Ny Nz]secondFieldsecond F-space field with shape[Nx Ny Nz]
Returns
spectrumreal cross-spectrum with shape[Nj Nkl]
Discussion
Compute a real modal cross-spectrum using the F-basis transform.
The result is the normalized real part of the product of the first transformed field and the complex conjugate of the second.
