sym_get_matrix

int sym_get_matrix(sym_environment *env, int *nz, int *matbeg, int *matind, 
		   double *matval)

Description:

This routine is used to get the constraint matrix in a standard column-ordered format.

Arguments:

sym_environment *env	IN	Pointer to the SYMPHONY environment.
int *nz	OUT	Pointer to integer indicating the non zero elements of the constraint matrix.
int *matbeg	OUT	Pointer to a double type array to be filled by the starting positions of each of column. Note that, the size of this array has to be at least the number of columns+1
int *matind	OUT	Pointer to a double type array to be filled by the row indices corresponding to each entry of matval. Note that, the size of this array has to be at least the number of nonzero elements of the constraint matrix.
int *matval	OUT	Pointer to a double type array of the values of nonzero entries of the constraint matrix in column order. Note that, the size of this array has to be at least the number of nonzero elements of the constraint matrix.

Return values:

FUNCTION_TERMINATED_ABNORMALLY	Function invoked unsuccessfully.
FUNCTION_TERMINATED_NORMALLY	Function invoked successfully.
