int CPXPUBLIC CPXgetcoef(CPXCENVptr env, CPXCLPptr lp, int i, int j, double * coef_p)

Definition file: cplex.h

The routine CPXgetcoef is used to access a single constraint matrix coefficient of a CPLEX problem object. The row and column indices must be specified.

Example

 status = CPXgetcoef (env, lp, 10, 20, &coef);

Parameters:

env	A pointer to the CPLEX environment as returned by `CPXopenCPLEX`.
lp	A pointer to a CPLEX problem object as returned by `CPXcreateprob`.
i	An integer indicating the numeric index of the row.
j	An integer indicating the numeric index of the column.
coef_p	A pointer to a double to contain the specified matrix coefficient.

Returns:

The routine returns zero on success and nonzero if an error occurs.
