Invert potential vorticity, returning streamfunction.

Streamfunction is determined from potential vorticity by subtracting the beta and orography terms and then solving the resulting elliptic equation.

Parameters

[in]	nx	Zonal grid dimension
[in]	ny	Meridional grid dimension
[out]	x	Streamfunction
[in]	pv	Potential vorticity
[in]	x_north	Streamfunction on northern wall
[in]	x_south	Streamfunction on southern wall
[in]	rs	Orography
[in]	deltax	Zonal grid spacing (non-dimensional)
[in]	deltay	Meridional grid spacing (non-dimensional)
[in]	f1	Coefficient in PV operator
[in]	f2	Coefficient in PV operator
[in]	bet	NS Gradient of Coriolis parameter
