void sofa::component::solidmechanics::fem::elastic::FastTetrahedralCorotationalForceField< DataTypes >::addKToMatrix	(	sofa::linearalgebra::BaseMatrix *	matrix,

overridevirtual

Internal addKToMatrix Overloaded function, usually called from the generic addKToMatrix version. This addKToMatrix version directly gives access to the matrix to fill, the stiffness factor and the offset used to identify where the force field must add its contributions in the matrix.

Parameters

matrix	the global stiffness matrix in which the force field adds its contribution. The matrix is global, i.e. different objects can add their contribution into the same large matrix. Each object adds its contribution to a different section of the matrix. That is why, an offset is used to identify where in the matrix the force field must start adding its contribution.
kFact	stiffness factor that needs to be multiplied to each matrix entry.
offset	Starting index of the submatrix to fill in the global matrix.
