interface

Type	Intent	Attributes		Name
class(tdc),	intent(inout)		::	this	The routine is called on this time dependent coordinate object.
integer(kind=ip),	intent(in)		::	ielem	The index of the element that contains the coordinate transformation information.
integer(kind=ip),	intent(in)		::	dir	The index of the boundary within the element that contains the coordinate transformation. Left boundary: 1, right boundary: 2.
complex(kind=wp),	intent(in),	dimension(:)	::	dudlambda	The vector of $\frac{\partial\Psi}{\partial\lambda}$ values to transform.
complex(kind=wp),	intent(in),	dimension(:)	::	dudxi	The vector of $\frac{\partial\Psi}{\partial\xi}$ values to transform.
complex(kind=wp),	intent(out),	dimension(:)	::	dudt	On output contains the $\frac{\partial\Psi}{\partial t}$ vector.
complex(kind=wp),	intent(out),	dimension(:)	::	dudrstar	On output contains the $\frac{\partial\Psi}{\partial r_*}$ vector.

Routine to transform from time dependent $(\lambda,\xi)$ to tortoise coordinates $(t,r_*)$ for complex vector input at element boundaries.
