Constructor & Destructor Documentation

INIT_ENCL::~INIT_ENCL ( ) [inline, virtual]
 

Destructor.

INIT_ENCL::INIT_ENCL ( int max_order,
const string & name ) [inline, protected]
 

Constructor.

Parameters:
max_order   maximum order allowed
name   name of the method

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

Member Function Documentation

bool INIT_ENCL::Validate ( INTERVAL_VECTOR & Y,
INTERVAL_VECTOR & LocErr,
double & h,
int order,
PtrODENumeric ODE,
PtrODESolver Solver ) [pure virtual]
 

Validates existence and uniqueness and computes a priori bounds.

This function tries to validate existence and uniqueness of the solution. If successful, it returns an enclosure of the solution, an enclosure of the local error, and a stepsize.

Parameters:
Y   (output) an enclosure of the solution
LocErr   (output) an enclosure of the local error
h   (input/output) stepsize
order   order of the method
ODE   pointer to a problem
Solver   pointer to a solver

Precondition:
h != 0 && order>0 && Order<=GetMaxOrder() && NotNull(ODE) && NotNull(Solver)

Returns:
true if existence and uniqueness have been established, and false otherwise.

Reimplemented in HOE.

void INIT_ENCL::Init ( PtrODENumeric ODE ) [pure virtual]
 

Initializes the method.

Parameters:
ODE   pointer to an object representing the numerical problem
Precondition:
NotNull(ODE)

Reimplemented in HOE.

int INIT_ENCL::GetMaxOrder ( ) const [inline]
 

Returns the maximum order allowed.
