I have a lot of text files in the form:
(0000000000)
(2020231032)
(0222320033)
(3120030223)
(0001132233)
And I want to import them as arrays. When I get rid of the clammers and use dlmread, it reads each row as one big number, but I need them as row vectors of the given length. Is there a way to read the file as the array I wish, or maybe a function that inserts comma after every number?

How do you want to load each row into array? Giving an example output based on the lines in question will be helpful

Try this
file = fopen('filename.txt');
data = textscan(file, '(%1d%1d%1d%1d%1d%1d%1d%1d%1d%1d)');
fclose(file);
data = cell2mat(data);

Following code will work on arbitrary number of digits
file = fopen('temp.txt');
data = textscan(file, '%s');
fclose(file);
result = cell2mat(cellfun(@(x) sscanf(x(2:end-1), '%1d'), data{1}, 'UniformOutput', 0)')';
