How to open file array with fopen?

Hi, I have a list of files that look like this:

J={'File1', 'File2', 'File3'}

It is not possible to open the file using fopen this way:

 for i=1:length(J)

   fid=fopen('J(1)', 'r')

   %Some algorithms here...

   fclose(fid)

 end

Is there any possible way to use fopen by using looping? It seems like it only accepts the actual file name. Please help. Thanks!

You just need to index into J properly. J looks to be a cell array so you need to use curly brackets.

Try replacing your fopen line with this

fid = fopen(J{i},'r');

It works. I thought I did that and it it didn't work. It must be something that I missed earlier on. Thank you so much for pointing that out for me.
