| Oct 31, 2014 at 17:13 | comment | added | Nate Eldredge | What is your metric for "best approximation"? Given continuous $f$, you want to find a continuous piecewise linear $g$ with $n$ knots that minimizes... what? The uniform distance between $f$ and $g$? The $L^2$ distance? Something else? | |

| Oct 29, 2014 at 15:15 | comment | added | denny | I mean best approximation on whole function domain. "fitting given curve and given number of knots" - I mean constructing continuous piecewise linear function for given curve (actually sets of points). Number of knots of this continuous piecewise linear function is restricted by some fixed value N but their positions must be optimal (give the best approximation). | |
| Oct 29, 2014 at 14:58 | comment | added | j.c. | You should give some more details. What do you mean by optimal? I also don't know what you mean by "fitting given curve and given number of knots". | |
