binary

binary is used to constrain a variable to be binary.

Syntax

F = binary(x)

Examples

Setting up a binary linear program can be done as

x = binvar(n,1);
optimize(A*x<=b,c'*x)

or

x = sdpvar(n,1);
optimize([A*x<=b, binary(x)],c'*x)

The binary constraint is imposed on the involved variables, not the actual expression. Hence, the following two constraints are equivalent

F = binary(x);
F = binary(pi+sqrt(2)*x);

Comments

If possible, use binvar instead as there are some parts in YALMIP where it can exploit integrality on an earlier stage if the varaibles have been defined as such.
