| Post subject: | not-a-knot condition |
Hi everyone; I am new to alglib. what I am trying to do is implement something like spline in matlab. my question is: how can I set "not-a-knot" condition in spline1dbuildcubic function. Indeed I do not have much about not-a-knot end condition (I saw it in matlab documentation) and I am getting some different values than matlab when I run my application. I think the reason is something related to end point conditions. any idea appreciated. thanks. p.s. if my problem is not clear please feel free to tell me so that I can clearify it more. |

Current version of ALGLIB does not include not-a-knot boundary conditions. If you just need good spline, you can use parabolically terminated splines - they are good enough for most practical purposes. |
