bilinear_interpolation_array(z00, z10, z01, z11, x, y, res)

2D interpolation Applies linear interpolation across x and y between xmin,xmax and ymin,ymax. x, y and z must be 1D-arrays of the same length.

Parameters:

• z00 (array) – Array corresponding to xmin,ymin

• z10 (array) – Array corresponding to xmax,ymin

• z01 (array) – Array corresponding to xmin,ymax

• z11 (array) – Array corresponding to xmax,ymax

• x (array) – weights on x coord

• y (array) – weights on y coord

interp_ind_weights(x_to_interp, x_grid)

Finds the indices and weights to interpolate from a x_grid to a x_to_interp.

roots(a, b, c)

Find roots of a polynomial, i.e., find x for \(ax^2 + bx + c = 0\).
