modesAtQuadraturePoints

Return resolved modes on mode-adapted quadrature points.

---

Declaration

 [F,G,h,zq] = modesAtQuadraturePoints(self,options)

Parameters

• self InternalModesSpectral instance
• options.nPoints number of quadrature points and modes requested
• options.omega fixed frequency in radians per second; specify either omega or k
• options.k fixed horizontal wavenumber; specify either omega or k

Returns

• F horizontal-velocity mode matrix on zq
• G vertical-velocity mode matrix on zq
• h equivalent-depth row vector
• zq quadrature-point depth locations

Discussion

This helper chooses quadrature points from the roots of a resolved higher mode, temporarily evaluates the requested modes on those points, and restores the original output grid before returning.
