Hi! I'm trying to learn MATL, and I can't figure out why dt?ZS behaves the same as dt? i.e. the ZS seems to have no effect: tio.run/##y00syfn/P6XE/r9qtIECGMZyqUYbKRgrmCiYQpjmCkYKpgqGCpax/…

Probably some dumb mistake from me, but I dunno what it is...

(To be clear, I expected the output to be [-1 1 -1 0])

Oh... Even dumber than I thought, the if condition just isn't satisfied, dunno what I was thinking.
