size(object)A Constraint object.
The tolerance for checking if the constraint is violated.
A numeric scalar, vector, or matrix.
dim(Constraint): The dimensions of the constrained expression.
size(Constraint): The size of the constrained expression.
is_real(Constraint): Is the constraint real?
is_imag(Constraint): Is the constraint imaginary?
is_complex(Constraint): Is the constraint complex?
is_dcp(Constraint): Is the constraint DCP?
is_dgp(Constraint): Is the constraint DGP?
residual(Constraint): The residual of a constraint
violation(Constraint): The violation of a constraint.
constr_value(Constraint): The value of a constraint.
get_data(Constraint): Information needed to reconstruct the object aside from the args.
dual_value(Constraint): The dual values of a constraint.
dual_value(Constraint) <- value: Replaces the dual values of a constraint..
size(ZeroConstraint): The size of the constrained expression.
