Error Opening File with readtable

I am trying to open couple of files in different directories all that have the same name, because it is a long list (I only attached a short list here) I put it in a for loop. I know that the file does exist and that the path is correct from where I run.

for name = {'747','585','9555'}
	filename = '/sort_pos.txt';
	filename = strcat(name,filename);
	A = table2array(readtable(filename,'Format','%f\t%f\t%f'));
end

The error I get is:

"Error using readtable (line 143)

Input must be a row vector of characters."

Any help would be amazing, thanks!

Inside your loop name is a cell array of character vector and strcat involving it is going to return a cell array of character vector which readtable cannot process.

fullfile(name{1}, 'sort_pos.txt')
