bottomModesAtWavenumber

Return the analytical bottom SQG mode for exponential stratification.

---

Declaration

 psi = bottomModesAtWavenumber(self,k)

Parameters

• self InternalModesExponentialStratification instance
• k horizontal wavenumber array

Returns

• psi bottom SQG mode evaluated on zOut

Discussion

        Not done in LaCasce 2012, but the calculation is almost   identical.   size(psi) = [size(k); length(z)]
