Purpose
Get a constraint
coefficient or constant term.
Synopsis
function getcoeff(c:linctr):real
function getcoeff(c:linctr, x:mpvar):real
Arguments
c

A linear constraint

x

A decision variable

Return value
Coefficient of the variable or the constant term.
Example
In this example a single constraint with three variables is defined. The calls to getcoeff result in r taking the value 1 and s taking the value 12.
declarations
x,y,z:mpvar
enddeclarations
c:= 4*x + y z <= 12
r:= getcoeff(c, z)
r:= getcoeff(c)
Further information
This function returns the coefficient of a given variable
in a constraint, or if no variable is given, the constant term
(= RHS) of the constraint. The returned values correspond to a
normalised constraint representation with all variable and constant
terms on the left side of the (in)equality sign.
