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);

A = dlmread(sprintf('gr_at_0.l_%d',j));
