OCC.AppCont module

This package provides the least square algorithmsnecessary to approximate a set of continous curvesor a continous surface.It also provides an instantiation of these algorithmsfor a class Function, a function f(t).The user will have to inherit class Function to use it.-Level : Advanced.All methods of all classes will be advanced.

class AppCont_Function(*args, **kwargs)
