use function many times with different folders as input

I have a function where you can give a folder as input. This function works perfectly.

I have to use this function many times with different folders as input. I made something like this, but it does not work:

dir1={‘C:\folder\subfolder1\subfolder2\subfolder3\A\01',’C:\folder\subfolder1\subfolder2\subfolder3\B\01’};

for i=1:length(dir1)
   dir1=dir1{i};

     [theta,omega]=program(dir1);     % The program which works outside of the list

end

it gives the error:

“Cell contents reference from a non-cell array object. 
Error in run (line 19)”

Line 19 is the dir1=dir{i}. I assume this is the error because dir1 is a folder with data, and not one datapoint? How can I use the program [theta,omega]=program(dir1,dir2) for different folders?

Don't do this:

dir1=dir1{i};
[theta,omega]=program(dir1);

You just blew away dir1 by replacing it with only one of the items in the list. Do this:

[theta,omega]=program(dir1{i});

Thank you for your explanation! It works now!

Your Dir1 is missing an apostrophe (')

You have not given a value to dir1, only to Dir1

I am sorry, I did not copy the code but wrote it again in word and made a few mistakes! I changed it!

You were missing 3 apostrophes. You had both forward and backward tilting ones, plus one normal one. Use only straight, vertical apostrophes. After that, are you still having a problem? If not, mark the answer as accepted to close it out.
