'Matrix dimensions must agree' error on string operations
显示 更早的评论
My code looks like:
data is 2x1 array.
data =
{'cont_box_A'}
{'cont_box_B'}
I'm trying to compare the string to another string, like:
if(data{1} == 'Test')
fprintf('Not the same')
else
fprintf('Same')
end
When I try to execute this, I get an error saying 'Matrix dimensions must agree'. don't really know what's wrong.

"...don't really know what's wrong."
What you wrote performs an element-wise comparison of the character in two character arrays. Just like for numeric arrays, that operation requires that the arrays have compatible sizes (exactly as described in the documentation, so I won't copy it here).
But what you are trying to do is to compare the entire strings, for which you should use strcmp or strcmpi:
strcmp(data{1},'Test')

ismember(data{1}, 'Test')
