MATLAB: How to open file array with fopen

Question

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!

Answer 1

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');
