Hi,
This seems not to work as intended:
>> str2num('"Y"')
ans =
"Y"
This should return an empty array.

Can't reproduce that here w/ R2019b. Which release?
Tried clear str2num yet first?

In r2020a:
>> str2num('"Y"')
ans =
[]
as expected, since it's not a number. So the best answer is to upgrade. Can you do that? Are you on the maintenance plan?

Well, my company is, but I've just merged to R2018b a month ago or so. So upgrading is not going to happen soon... Anyway, I'll work my way around it then.
