The function quadratic_interpolation interpolates the function values and first degree functions defined from the function gradients. Both, function values and gradients, must be provided by functors.

This function generates the
interpolated function value as the weighted sum of the values plus a
linear term in the gradient for each point of the point/coordinate
pairs in the range first,
beyond. See also
sibson_c1_interpolation. Precondition: norm function_value(p).second == true for all points p of the point/coordinate pairs in the range first, beyond. |
