Hi, I am new to the ALGLIB library. I am currently trying to interpolate a set of points with given gradients but limited by the maximum and minimum second derivatives. May I know how can I go about using the library or whether this is achievable with this library? PS: Sorry for the noobie question but I am overwhelmed by the information available on the documentation site. |

Is it 1D interpolation, 2D or more? What kind of interpolation you want to use - polynomial, spline, etc.? |

Basically I am trying to interpolate points (in x and y coordinates) with their respective gradients with a minimum and maximum second derivatives. So I guess I need a 2D interpolation using spline. Thanks. |
