Functions

polyfit2d(x, y, z, kx, ky, *[, order, weights])	Two dimensional polynomial fitting by least squares.
polyfit2d_eval(x, y, soln, kx, ky)	Evaluate polynomial fit from polyfit2d()
polyfit2d_index(kx, a, b)	Returns index of polynomial from the result of polyfit2d() for \(x^{a} y^{b}\).
polyfit2d_indices(kx, ky)	Get indicies of polynomials returned by polyfit2d().
