Usage of validateattributes with 'nonzero'
显示 更早的评论
I am wondering whether this is a bug:
validateattributes([0 0 1],{'numeric'},{'nonzero'})
Should result in an error, but the test passes as long as at least one element of the vector is nonzero. The function documentation says otherwise.

Which version of Matlab are you using? In R2017b:
>> validateattributes( [0 0 1], { 'numeric' }, { 'nonzero' } )
Expected input to be nonzero.
so it looks to be working fine. Maybe it is a bug in an older version though. Strangely, in all my thousands of usages of validateattributes over the years I have never actually used 'nonzero' so hadn't even realised it existed as an attribute!

Hmm, I don't have R2015b or earlier installed any more, but it works in R2016a. Maybe it was fixed for that version.

That should certainly work fine
