Hi, I am new to use ALGLib for curve fitting. Can I set the constraint of the coefficient of the curve so that they are not outside the boundary? And is it capable to fit the curve below? if x > 0, y = a* x^2 + b * x +c else, y = (a+b)/2 * x^2 + b * x +c Regards, Dophine |

Hello! LSFit subpackage allows you to perform bound constrained fitting - and to fit by custom functions like yours. I recommend you to study Reference Manual and examples. |
