Transposing cell arrays is behaving like cellfun

I was having some strange errors, and eventually figured out that this was going on. Take a simple example.

a = cell(1, 2)
a{1} = 'wx'
a{2} = 'yz'

Now, let's transpose.

EDU>> aT = a'

aT = 

      [2x1 char]    [2x1 char]

EDU>> size(aT)

ans =

       1     2

EDU>> size(a)

ans =

       1     2

EDU>> aT{1}

ans =

w
x

Isn't this weird? Did I change some setting or something that is messing this up?

That's not what I get. I get that aT is a 2x1 cell array, as you expected.

Could you have somehow redefined the ctranspose function, which is what the "apostrophe" calls? What you do you get when you type

which -all ctranspose

?

Absolutely right! A third-party library contained a function called ctranspose which caused the incorrect behavior. After removing it, things worked again. Thanks!
