Is it possible to use exist function in a loop?

for i=1:5
 filename_1 = ['E:\Abhi\file_',num2str(i)];
 save (filename_1)
end

for j=1:9
    filename_1 = ['E:\Abhi\file_',num2str(j)];
    exist('filename_1','file')       % not sure how to write this exactly
end
here I expect to get answer 2 for file_1 to file_5 and for rest others as 0.

Thanks.

Answer 1

Did you try it? The help for EXIST indicates you can use it as you are doing.

Yes. I tried following also but not working

exist('filename_1.mat','file')

exist([filename_1,'.mat'],'file')

Thank you very much!
