Class Equality#
Defined in Program listing for file kernel/src/simulationTools/Equality.hpp
-
class Equality : public LinearOSNS#
Formalization and Resolution of a Linear Complementarity Problem (Equality)
Aim of the Equality class#
This class is devoted to the formalization and the resolution of the Linear system (Equality) defined by : \( 0 = w = q + M z \) where
\( w \in R^{n} \) and \(z \in R^{n} \) are the unknowns,
\( M \in R^{n \times n } \) and \(q \in R^{n} \)
The Equality main components are:
a problem (variables M,q and size of the problem), which directly corresponds to the LinearComplementarityProblem structure of Numerics
the unknowns z and w
Public Functions
-
Equality(int numericsSolverId = 0)#
constructor from data
- Parameters:
numericsSolverId – id of numerics solver, default = 0
-
Equality(SP::SolverOptions options)#
constructor from a pre-defined solver options set.
- Parameters:
options, the – options set,
see Nonsmooth problems formulations and available solvers for details.
-
