				function x = false(x)
				% FALSE Constrains a variable to be negative
				%
				% FALSE(x) returns the constraint set(x				%
				% Example
				%
				% SET(FALSE(a))    constrains binary variable a to be 0 (i.e. false)
				% SET(FALSE(a|b))  constrains binary variables a and b to be 0 (i.e. false)
