double stepSize

(

)

const [inline]

Get step size

Reimplemented from GslGenericSolver.

void setStepSize

(

double

stepSize

)

[inline]

Set step size

Reimplemented from GslGenericSolver.

void setDimension

(

int

dimension

)

[inline, virtual, inherited]

Set ODE dimension

Reimplemented from Solver.

void setToleranceAbs

(

double

toleranceAbs

)

[inline, virtual, inherited]

Set absolute allowed local tolerance

Reimplemented from Solver.

void setToleranceRel

(

double

toleranceRel

)

[inline, virtual, inherited]

Set relative allowed local tolerance

Reimplemented from Solver.

virtual void setFunction

(

Function

function

)

[inline, virtual, inherited]

Set callback function

void setParams

(

void *

params

)

[inline, virtual, inherited]

Set callback function params

Reimplemented from Solver.

void doCalcFn	(	double *	t,
		double	y[],
		double	f[] = 0
	)			[virtual, inherited]

Calculate function value

Implements Solver.

bool doEvolve	(	double *	t,
		double	t1,
		double	y[],
		double	yerr[]
	)			[virtual, inherited]

Integrate.

Parameters:

	t	Current time (will be updated by the new value)
	t1	Target time
	y[]	Current function value
	yerr[]	Array to store local errors

Returns:

true on success, false on failure (too big local error)

Todo:

Provide error message

Implements Solver.
