％CHECKBOUNDS Move the initial point within the (valid) bounds.

％ [X,LB,UB,X,FLAG] = CHECKBOUNDS(X0,LB,UB,nvars)

％ checks that the upper and lower

％ bounds are valid (LB <= UB) and the same length as X (pad with -inf/inf

％ if necessary) warn if too long. Also make LB and UB vectors if not

％ already.

％ Finally, inf in LB or -inf in UB throws an error.
