Inverse bilinear interpolation

Module Contents

effluent.numerics.bilin_inv(f, g, F, G, maxiter=7, tol=1e-07)

Inverse bilinear interpolation

f, g should be scalars or arrays of same shape

F, G should be 2D arrays of the same shape

Parameters:

• f – Desired f value

• g – Desired g value

• F – Tabulated f values

• G – Tabulated g values

• maxiter – Maximum number of Newton iterations

• tol – Maximum residual value

Returns:

A tuple (x, y) such that F[x, y] = f and G[x, y] = g, when linearly interpolated
