Opening different files in for loop with dlmread?

I'm trying to open .txt files caesar1, caesar2, and caesar3 in a for loop.
for k = 1:3
N = string([1,2,3]);
caesarN = strcat('caesar',N);
caesarT = strcat(caesarN, '.txt');
caesar(k) = dlmread(caesarT);
end
I do end up getting a string array caesarT = [caesar1.txt, caesar2.txt, and caesar3.txt] but dlmread won't open them for some reason (says that Filename must be a character vector). I tried to char(caesarT), but it still doesn't work. What am I missing here? Do I just need to somehow add the characters ' ' to my caesar# strings? (e.g. literally have the string be 'caesar1.txt'... instead of caesar.txt)

You need to call one file at a time in dlmread. Change to:
for k = 1:3
N = string([1,2,3]);
caesarN = strcat('caesar',N);
caesarT = strcat(caesarN, '.txt');
caesar(k) = dlmread(caesarT{k});
end
You can also use something like this, to generate the names
fnames = dir('filepath\ceasar*');
all files in the current dir beginning with 'ceasar' are stored in fnames.name
