Function File: [UV] = tforminv (T, XY)

Function File: [U, V] = tforminv (T, X, Y)

Given a transform structure T, transform coordinates XY in the output space into coordinates UV in the input space.

Input and output coordinates may be given/retrieved either as a n-by-2 array, or as two n-by-1 vectors.

The function makes use of the "inverse_fcn" field of the transform structure T, which should thus be defined.
