DESCRIPTION

Stores a field sequence together with its associated parameter value: a branch variable represents a pair (t,uh(t)) for a specific value of the parameter t. Applications concern time-dependent problems and continuation methods.

This class is convenient for file inputs/outputs and building graphical animations.

EXAMPLES

Coming soon...

LIMITATIONS

This class is under development.

The branch class store pointers on field class without reference counting. Thus, branch automatic variables cannot be returned by functions. branch variable are limited to local variables.
