KmlScaissCsiSolveDx?I

Solve a system of linear algebra equations. Each process reads and stores its corresponding solution result.

C interfaces:

int KmlScaissCsiSolveDxSI(KmlScasolverTask **handle, int nb, float *x, int ldx, const float *b, int ldb);

int KmlScaissCsiSolveDxDI(KmlScasolverTask **handle, int nb, double *x, int ldx, const double *b, int ldb);

Parameter	Type	Description	Input/Output
handle	KmlScasolverTask **	Solver handle, which is a variable passed from a previous step.	Input/Output
nb	int	Number of RHS vectors. The value of nb can only be 1.	Input
x	float * in KmlScaissCsiSolveDxSI double * in KmlScaissCsiSolveDxDI	Array that reads and stores the solution result corresponding to the current process. The number of elements is the number of rows in the matrix corresponding to the current process, that is, stripeWidth.	Input/Output
ldx	int	Size of the leading dimension of x. This is a reserved parameter.	Input
b	const float * in KmlScaissCsiSolveDxSI const double * in KmlScaissCsiSolveDxDI	Local RHS array corresponding to the current process. The number of elements is the number of rows in the matrix corresponding to the current process, that is, stripeWidth.	Input
ldb	int	Size of the leading dimension of b. This is a reserved parameter.	Input

Return Value	Type	Description
KMLSS_NO_ERROR	int	The execution is successful.
KMLSS_BAD_NB	int	The value of nb is not 1.
KMLSS_NO_MEMORY	int	The memory is insufficient.
KMLSS_NULL_ARGUMENT	int	A null parameter exists in {handle, x, b}.
