comment On the notion of positive rank of a matrix
instead of "So what is preventing 0−1 or finite positive alphabet matrix to have such separation?", if I ask "So what is preventing a generic positive matrix to have such separation?", is there an explanation? In essence I am asking if we have no alphabet restriction except positive entries, would such separation be rare finds?

@DavidSpeyer can we say same about 0-1 matrices?

comment Fixed points of self maps
I already noticed it. but I thought it is clear I want only $m$ points fixed (added only to sentence there).

comment Complexity of Approximating Vandermonde Determinant
true.. if the number had structure, could we do better? without structure we cannot do better.
