fid = fopen('filename.txt');
out=textscan(fid,'%s')
fclose(fid);
out=reshape(out{:},4,[])'

I am trying to read multiple files i changed the code like this but i am getting some errors it says invalid identifier
for j =1:4
fid(j) = fopen( sprintf( 'Secret1%i.obj',j),'r' )
out(j)=textscan(fid(j),'%s')
fclose(fid(j));
out{j}=reshape(out{:},4,[])'
end
