void Kratos::EigenDenseDirectSolver< TSolverType, TSparseSpaceType, TDenseSpaceType, TReordererType >::InitializeSolutionStep ( MatrixType rA,
VectorType rX,
VectorType rB 
)
inlineoverridevirtual

This function is designed to be called every time the coefficients change in the system that is, normally at the beginning of each solve. For example if we are implementing a direct solver, this is the place to do the factorization so that then the backward substitution can be performed effectively more than once

Parameters
rASystem matrix
rXSolution vector
rBRight hand side vector
