This formula is one of the constraints, and I don’t know how to express it in cvx

If `alpha`

is a vector variable or expression to be constrained to the continuous interval `[0,1]`

, use `0 <= alpha <= 1`

.

However, if `{0,1} `

actually means that alpha can only takes the value 0 or 1, and not any value in the continuous interval `[0,1]`

, you should declare `alpha`

as binary, in which case specifying `0 <= alpha <= 1`

is redundant

It actually means that alpha can only takes the value 0 or 1 (the each element in the matrix only takes the value 0 or 1). How should I declare each element as binary?

If `alpha`

is a k by 1 vector variable:

`variable alpha(k) binary`

Thanks a lot!!!
