XPRSchgobj

XPRSchgobj


Purpose
Used to change the objective function coefficients.
Synopsis
int XPRS_CC XPRSchgobj(XPRSprob prob, int nels, const int mindex[], const double obj[]);
Arguments
prob 
The current problem.
nels 
Number of objective function coefficient elements to change.
mindex 
Integer array of length nels containing the indices of the columns on which the range elements will change. An index of -1 indicates that the fixed part of the objective function on the right hand side should change.
obj 
Double array of length nels giving the new objective function coefficient.
Example
Changing three coefficients of the objective function with XPRSchgobj :
mindex[0] = 0; mindex[1] = 2; mindex[2] = 5;
obj[0] = 25.0; obj[1] = 5.3; obj[2] = 0.0;
XPRSchgobj(prob,3,mindex,obj);
Further information
The value of the fixed part of the objective function can be obtained using the OBJRHS problem attribute.
