Function Documentation

printOutput()

void printOutput	(	double *	grid,
		int	dimension
	)

Prints the output in text format

Parameters

[in]	grid	double precision array containing the first grid buffer
[in]	dimension	the size of the system. The buffers should be of size (dimension + 2)^2

setBoundaryConditions()

void setBoundaryConditions	(	double *	grid,
		double *	gridNew,
		int	dimension
	)

Sets the boundary conditions on both the grid buffers

Parameters

[in]	grid	double precision array containing the first grid buffer
[in]	gridNew	double precision array containing the second grid buffer
[in]	dimension	the size of the system. The buffers should be of size (dimension + 2)^2

update()

void update	(	double *	grid,
		double *	gridNew,
		int	dimension
	)

Performs one step of the Jacobi iteravite process

Parameters

[in]	grid	double precision array containing the first grid buffer
[in]	gridNew	double precision array containing the second grid buffer
[in]	dimension	the size of the system. The buffers should be of size (dimension + 2)^2
