Documentation

The Linear class is an algorithmic class which uses the linear solution algorithm to solve the equations. This is based on a Taylor expansion of the linear system \R(\U) = \zero about an approximate solution \U_{a}.

which can be expressed as:

which is solved for \Delta \U to give the approximation \U = \U_{a} + \Delta \U.

Linear()

The integer EquiALGORITHM_TAGS_Linear (defined in <classTags.h>) is passed to the EquiSolnAlgo classes constructor.

~Linear()
