Description:

This routine is used to load a problem description into SYMPHONY manually. The constraint matrix is passed in a standard column-ordered format. The arguments here are the same as the fields in the MIPdesc data structure discussed in Section 6.3.2.1. Please see the discussion there for a more detailed description of the arguments here.

Arguments:

sym_environment *env	INOUT	Pointer to the SYMPHONY environment.
int numcols	IN	Number of the columns.
int numrows	IN	Number of the rows.
int *start	IN	Array of the starting positions of each of column.
int *index	IN	Array of the row indices corresponding to each entry of value.
int *value	IN	Array of the values of nonzero entries of the constraint matrix in column order.
double *collb	IN	Array of the lower bounds of the columns.
double *colub	IN	Array of the upper bounds of the columns.
double *obj	IN	Array of the objective function coefficients.
double *obj2	IN	Array of the second objective function coefficients when multi criteria solver is to be used.
char *rowsen	IN	Array of the senses of the constraints.
		'L': $\leq$ constraint
		'E': = constraint
		'G': $\geq$ constraint
		'R': ranged constraint
		'N': free constraint
double *rowrhs	IN	Array of the right hand side values.
double *rowrng	IN	Array of the row ranges.
		(sym_get_row_upper) - (sym_get_row_lower) if the row sense is 'R', 0 otherwise.
char make_copy	IN	SYMPHONY will create the copies of these arrays for internal usage if this flag is set to true, otherwise, will own them.

Return values:

ERROR__USER	Error. User error detected in
	user_initialize_root_node function.
FUNCTION_TERMINATED_ABNORMALLY	Function invoked unsuccessfully.
FUNCTION_TERMINATED_NORMALLY	Function invoked successfully.
