crossSpectrumWithGgTransform

Compute a real modal cross-spectrum using the G-basis transform.

---

Declaration

 spectrum = crossSpectrumWithGgTransform(firstField,secondField)

Parameters

• firstField first G-space field with shape [Nx Ny Nz]
• secondField second G-space field with shape [Nx Ny Nz]

Returns

• spectrum real cross-spectrum with shape [Nj Nkl]

Discussion

Compute a real modal cross-spectrum using the G-basis transform.

The result is the normalized real part of the product of the first transformed field and the complex conjugate of the second.
