CPXgetcoef

Description

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.

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

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

Arguments

The pointer to the CPLEX environment as returned by CPXopenCPLEX().

A pointer to a CPLEX problem object as returned by CPXcreateprob().

An integer indicating the numerical index of the row.

An integer indicating the numerical index of the column.

A pointer to a double to contain the specified matrix coefficient.

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