| const CubicCartesianData calcCubicThroughPoints | ( | const std::vector< Coordinate > & | points | ) |
This function calcs a cartesian cubic equation such that the given points are on the cubic.
There can be at most 9 and at least 2 point. If there are less than 9, than the coefficients will be chosen to 1.0 if possible
