## Types

typedef unspecified_type Matrix

typedef unspecified_type Vector

typedef unspecified_type NT

## Creation

SparseLinearAlgebraTraits_d ()
Default constructor.

## Operations

bool linear_solver (const Matrix &A, const Vector &B, Vector &X, NT &D)
Solve the sparse linear system $$A \times X = B$$. More...

## ◆ linear_solver()

 bool SparseLinearAlgebraTraits_d::linear_solver ( const Matrix & A, const Vector & B, Vector & X, NT & D )

Solve the sparse linear system $$A \times X = B$$.

Return true on success. The solution is then $$(1/D) \times X$$.

Precondition
A.row_dimension() == B.dimension()
A.column_dimension() == X.dimension()
