setcoeff


Purpose
Set the coefficient of a variable or the constant term.
Synopsis
procedure setcoeff(c:linctr, x:mpvar, r:real)
procedure setcoeff(c:linctr, r:real)
Arguments
A linear constraint
A decision variable
Coefficient or constant term
Example
The following declares a constraint c and then changes some of its terms:
declarations
 x,y,z: mpvar
end-declarations

c:= 4*x + y -z <= 12 

setcoeff(c, y, 2)
setcoeff(c, 8.1)
The constraint is now 4·x + 2·y - z Maths/leq.png -8.1.
Further information
If a variable is given then this procedure sets the coefficient of this variable in the constraint to the given value. Otherwise, it sets the constant term of the constraint.
