I have a problem in cd command
for i=1:length(Arr)
cd(category{:,i});
..... etc
category is vector that contain directories names. when I try to run it, the following error comes: "Argument must contain a character vector"
What is the problem? How can I fix it?
I'm using matlab 2016 for mac thank you.

Your use of
cd(category{:,i});
suggests that you are extracting a row of elements rather than a single element. A single element would be expected to look like
cd(category{1,i});
or
cd(category{i});
