interpolation method requires knowledge of the function derivatives at the
control points, however we only know the function values. Consequently, we will
use the data to estimate derivatives at the control points. The choice of how to
compute the derivatives is not unique and Ceres uses the Catmull–Rom Spline
compute the derivatives is not unique and Ceres uses the Catmull-Rom Spline
variant which uses `0.5 * (p_{k+1} - p_{k-1})` as the derivative for control
point `p_k.` This produces a first order differentiable interpolating
function. The two dimensional interpolation scheme is a generalization of the
