XPRSaddnames

XPRSaddnames

Purpose
When a model is loaded, the rows, columns, sets, piecewise linear and general constraints of the model may not have names associated with them. This may not be important as the rows, columns, sets, piecewise linear and general constraints can be referred to by their sequence numbers. However, if you wish row, column, set, piecewise linear and general constraint names to appear in the ASCII solutions files, the names for a range of rows/columns/... can be added with XPRSaddnames.
Synopsis
int XPRS_CC XPRSaddnames(XPRSprob prob, int type, const char cnames[], int first, int last);
Arguments
prob 
The current problem.
type 
1 
for row names;
2 
for column names.
3 
for set names.
4 
for piecewise linear constraint names.
5 
for general constraint names.
cnames 
Character buffer containing the null-terminated string names.
first 
Start of the range of rows, columns, sets, piecewise linear or general constraints.
last 
End of the range of rows, columns, sets, piecewise linear of general constraints.
Example
Add variable names ( a and b), objective function ( profit) and constraint names ( first and second) to a problem: 
char rnames[] = "profit\0first\0second"
char cnames[] = "a\0b";
...
XPRSaddnames(prob,1,rnames,0,nrow-1);
XPRSaddnames(prob,2,cnames,0,ncol-1);
