CPXXgetx and CPXgetx
The routine CPXXgetx/CPXgetx accesses the solution values
for a range of problem variables.
int CPXXgetx( CPXCENVptr env, CPXCLPptr lp, double * x, CPXDIM begin, CPXDIM end )
int CPXgetx( CPXCENVptr env, CPXCLPptr lp, double * x, int begin, int end )
Description
The routine CPXXgetx/CPXgetx accesses the solution values
for a range of problem variables. The
beginning and end of the range must be specified.
Note:
If the solution was obtained by the dual simplex algorithm and is
not dual feasible then the function returns values with respect to
the dual phase I bounds. You can use
CPXXsolninfo and CPXsolninfo to query primal and dual feasibility
of a solution.
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. - x
-
An array to receive the values of the primal variables for the problem. This array must be of length at least (
end-begin+1). If successful,x[0]throughx[end-begin]contains the solution values. - begin
- An integer specifying the beginning of the range of variable values to be returned.
- end
- An integer specifying the end of the range of variable values to be returned.
Return
The routine returns 0 (zero) if successful and nonzero if an error occurs.Example
status = CPXgetx (env, lp, x, 0, CPXgetnumcols(env, lp)-1);See also the example lpex2.c in the
CPLEX User's Manual and in the standard distribution.
