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

c	A linear constraint
x	A decision variable
r	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 -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.
