}Trait to provide various solver implementations for systems of equations AX=B.
Associated Types
type Rhs
The right-hand side type (the type of B in the equation AX=B)
type Output
The output (solution) type (the type of X in the equation AX=B)
Required Methods
fn solve(&self, b: &Self::Rhs) -> Result<Self::Output, Error>
Solve the equation AX=B for X. Solution can either be exact (if possible) or approximate. Shortcut for calling solve_exact or solve_approx.
fn solve_exact(&self, b: &Self::Rhs) -> Result<Self::Output, Error>
Solve the equation AX=B for the exact solution X
Failures
Fails if no exact solution is possible for AX=B or the equation is improperly defined.
fn solve_symm(&self, b: &Self::Rhs) -> Result<Self::Output, Error>
Solve the equation AX=B for the exact solution X. Assumes A is a symmetric matrix. Only the upper-triangular portion of A is considered; no failure occurs if A is not symmetric.
Failures
Fails if no exact solution is possible for AX=B orthe equation is improperly defined.
fn solve_approx(&self, b: &Self::Rhs) -> Result<ApproxSoln<Self::Output>, Error>
Solve the equation AX=B for the approximate solution X.
Failures
Fails if no approximate solution is possible for AX=B or the equation is improperly defined.
