setdetrow


Purpose
Set the determining row for a variable.
Synopsis
procedure setdetrow(var:mpvar, row:linctr)
procedure setdetrow(var:mpvar, row:nlctr)
procedure setdetrow(row:linctr, var:mpvar)
procedure setdetrow(row:nlctr, var:mpvar)
Arguments
var 
The variable for which the determining row is provided
row 
The row that determines the value of the variable.
Further information
A row which is determining for a variable defines the value of that variable. This means that the variable is a derived value which is calculated in another part of the model. Some solvers will use such designations to refine their search, and in particular in sequential linear programming, a process called cascading makes use of determining rows. Please refer to the Xpress NonLinear Reference Manual (chapter 'Cascading') for more information.
