I'm pretty sure that is not necessary.
the y's depend only on the x's and the order of the M values.
In any case, I think the zeros in your original problem
will not be much of an issue.
I should rephrase: The array should contain values >= zero.
(negative values are an issue, but these can be scaled away easily. )
I'm not sure where that is coming from.
The y's are determined by the x's and by sets
of rows determined by the order of the M values, not their signs.
Only one y value in a column can be one.
