Parameters:
max_order   maximum order allowed
name   name of the method

Precondition:
max_order>0 && !name.empty()

Member Function Documentation

void TIGHT_ENCL::CompEncl ( INTERVAL_VECTOR & Ytight,
INTERVAL_VECTOR & LocErr,
const INTERVAL & h,
int order,
PtrODENumeric ODE,
PtrODESolver Solver ) [pure virtual]
 

Computes a tight enclosure.

This function computes a tight enclosure of the solution at 

 ODE->GetTcur() + h
Parameters:
Ytight   (output) enclosure of the solution
LocErr   (output) enclosure of the local error
h   enclosure of the stepsize
order   order of the enclosure method
ODE   pointer to a problem
Solver   pointer to a solver

Precondition:
NonZero(h) && order>0 && order<=GetMaxOrder() && NotNull(ODE) && NotNull(Solver) && ODE->GetSize() == Dimension(Ytight) && ODE->GetSize() == Dimension(LocErr)

Reimplemented in IHO, and ITS_BASE.

void TIGHT_ENCL::Init ( const PtrODENumeric ODE ) [pure virtual]
 

Initializes the enclosure method.

Parameters:
ODE   pointer to a problem
Precondition:
NotNull(ODE)

Reimplemented in IHO, ITS_BASE, and ITS_QR.

int TIGHT_ENCL::GetMaxOrder ( ) const [inline]
 

Returns the maximum order allowed.

This function returns the value that is set in the constructor of TIGHT_ENCL.

void TIGHT_ENCL::RearrangeColumns ( MATRIX & R,
const MATRIX & A,
const INTERVAL_VECTOR & R ) [protected]
 

Rearranges the columns of A.
