j = (i * 2000000);
A = dlmread('gr_at_0.l_%d', j);
I get the following error:
Error using sprintf
Invalid format.
Error in dlmread (line 71)
delimiter = sprintf(delimiter); % Interpret \t (if necessary)
Error in RDF (line 15)
A = dlmread('gr_at_0.l_%d', j);
the following file is one of the many files that I want to read:
'''gr_at_0.1_0'''
I would appreciate any comment.

What do you suppose that the following statement will do?
j = (i * 2000000);
Replace
A = dlmread('gr_at_0.l_%d', j);
by
A = dlmread(sprintf('gr_at_0.l_%d',j));
