How does the matlab for loop work on a column vs. row vector of strings?

displaying a vector of strings using a for loop gives different results with a column vector vs. a row vector, why is that?

words = ["this"; "is"; "text"]

words = 3×1 string array
    "this"
    "is"
    "text"

for word = words
    disp(word);
end

    "this"
    "is"
    "text"

for word = words'
    disp(word);
end

this
is
text

for iterates over columns, so if you give it a column vector, it iterates one time, with the loop variable taking the value of the whole column.

for col = eye(3)
    disp(col)
end

     1
     0
     0

     0
     1
     0

     0
     0
     1

Why? Because the powers that be decided that's how it should work.

From the documentation:

• To iterate over the values of a single column vector, first transpose it to create a row vector.

Thank you for the answer. I had read the for loop info incorrectly, not realizing it iterated with whole columns instead of iterating through the column. That could actually be useful!
