CPXgetqpcoef

int CPXPUBLIC CPXgetqpcoef(CPXCENVptr env, CPXCLPptr lp, int rownum, int colnum, double * coef_p)

Definition file: cplex.h

Include files: cplex.h

The routine CPXgetqpcoef accesses the quadratic coefficient in the matrix Q of a CPLEX problem object for the variable pair indexed by (rownum, colnum). The result is stored in *coef_p.

Example

 status = CPXgetqpcoef (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`.
rownum	The first variable number (row number in Q).
colnum	The second variable number (column number in Q).
coef_p	A pointer to a double where the coefficient should be stored.

Returns:

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