Functions
static double	sum1d (const symbol_function_t *fptr, const symbol_matrix_t *symbmtx, pastix_int_t cblknum)
	Template function to compute cost on a column-block based approach with a single update per column block.
static double	sum2d (const symbol_function_t *fptr, const symbol_matrix_t *symbmtx, pastix_int_t cblknum)
	Template function to compute cost on block based approach.
static double	sum2dext (const symbol_function_t *fptr, const symbol_matrix_t *symbmtx, pastix_int_t cblknum, double *blokcost)
	Template function to compute cost on block based approach which keeps the cost per block.
static double	recursive_sum (pastix_int_t a, pastix_int_t b, double(*fval)(const symbol_function_t *, const symbol_matrix_t *, pastix_int_t), const symbol_function_t *fptr, const symbol_matrix_t *symbmtx)
	Recursive function to compute the cost of the full symbolic structure with either sum1d(), sum2d(), or sum2dext().
Symbol statistical information subroutines
size_t	pastixSymbolGetNNZ (const symbol_matrix_t *symbptr)
	Computes the number of non-zero elements in L.
void	pastixSymbolGetFlops (const symbol_matrix_t *symbmtx, pastix_coeftype_t flttype, pastix_factotype_t factotype, double *thflops, double *rlflops)
	Computes the number of theoretical and real flops.
void	pastixSymbolGetTimes (const symbol_matrix_t *symbmtx, pastix_coeftype_t flttype, pastix_factotype_t factotype, double *cblkcost, double *blokcost)
	Computes the cost of structure for the costMatrixBuild() function.
