Detailed Description

template<class TMatrix, class TVector>
class sofa::component::linearsystem::CompositeLinearSystem< TMatrix, TVector >

Component acting like a linear system, but delegates the linear system functionalities to a list of real linear systems.

Using this component allows to assemble more than one global matrix. It is useful when only a partial assembly is necessary. For example, the first linear system is the global one, and the second one could be only the stiffness matrix.
