CPXXNETgetx and CPXNETgetx

The routine CPXXNETgetx/CPXNETgetx is used to access solution values or, equivalently, flow values for a range of arcs stored in a network problem object.

int CPXXNETgetx( CPXCENVptr env, CPXCNETptr net, double * x, CPXDIM begin, CPXDIM end )

int CPXNETgetx( CPXCENVptr env, CPXCNETptr net, double * x, int begin, int end )

Description

The routine CPXXNETgetx/CPXNETgetx is used to access solution values or, equivalently, flow values for a range of arcs stored in a network problem object.

For this routine to succeed, a solution must exist for the network problem object.

Arguments

env: A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
net: A pointer to a CPLEX network problem object as returned by CPXXNETcreateprob/CPXNETcreateprob.
x: Array in which to write solution (or flow) values for requested arcs. If NULL is passed, no solution vector is returned. Otherwise, x must point to an array of size at least (end-begin+1).
begin: Index of the first arc for which a solution (or flow) value is to be obtained.
end: Index of the last arc for which a solution (or flow) value is to be obtained.

Return

The routine returns 0 (zero) on success and nonzero if an error occurs.

Example


 status = CPXNETgetx (env, net, x, 10, 20);
