Curve Fitting Tool:一个图形用户界面工具,用户可以通过该工具选择数据、模型类型,并调整拟合选项。 nlinfit函数:用于拟合非线性表达式,需要用户定义拟合函数和初始参数值。 lsqcurvefit函数:类似于nlinfit,但提供了更多的控制和灵活性,适用于需要自定义目标函数或约束条件的场景。 fit函数:一个通用的拟合函数,支持多种拟合...
This fully functional curve fitting tool has no time restrictions and is excellent for straightforward nonlinear regression analysis. Check out an example of a model generated by ndCurveMaster 2D: Y = a0 + a1·ln5(x) + a2·x1/2 + a3·x1.3 + a4·ln2(x) + … + an·exp(x) Why...
