CPXXgetcoef and CPXgetcoef
The routine CPXXgetcoef/CPXgetcoef accesses a single
constraint matrix coefficient of a CPLEX problem object.
int CPXXgetcoef( CPXCENVptr env, CPXCLPptr lp, CPXDIM i, CPXDIM j, double * coef_p )
int CPXgetcoef( CPXCENVptr env, CPXCLPptr lp, int i, int j, double * coef_p )
Description
The routine CPXXgetcoef/CPXgetcoef accesses a single
constraint matrix coefficient of a CPLEX problem object. The row and column
indices must be specified.
Arguments
- env
-
A pointer to the CPLEX environment as returned by
CPXXopenCPLEX/CPXopenCPLEX. - lp
-
A pointer to a CPLEX problem object as returned by
CPXXcreateprob/CPXcreateprob. - i
- An integer specifying the numeric index of the row.
- j
- An integer specifying the numeric index of the column.
- coef_p
- A pointer to a double to contain the specified matrix coefficient.
Return
The routine returns 0 (zero) if successful and nonzero if an error occurs.Example
status = CPXgetcoef (env, lp, 10, 20, &coef);
