At the FindGraph library there are
more than 200 built-in famous 2-D curves from the areas of elementary mathematics,
transcendental functions, probability and statistics, optimization, and graphics.
|
You can investigate these curves and vary the number of parameters to discover the best model to describe your data.
The functions can be defined by typing them as text and so the program is very flexible.
The program allows you to build parametric line graphs X(u,v), Y(u,v) with formulas you input.
Any function may then be fitted to the data and the fit displayed graphically.
You can draw families of lines with a given step of parameter.
