	Solve the linear system by assigning the right-hand side to the solution. Implements \( x = b \).

Detailed Description

template<OperatorLike OperatorT>
class terra::linalg::solvers::IdentitySolver< OperatorT >

"Identity solver" for linear systems.

Implements a "no-op" solve operation by directly assigning the right-hand side to the solution vector: \( x \gets b \). Satisfies the SolverLike concept (see solver.hpp). Can be used as a placeholder for "no preconditioner".

OperatorT is essentially ignored (does not need to be the identity operator).

Template Parameters

OperatorT

Operator type (must satisfy OperatorLike).
