I keep getting this error "File identifier must be an integer-valued scalar of type double." when using fopen

I am trying to read in g-code text into matlabe using fopen and this error keeps appearing:

Could someone please help in deciphering this issue?

Here is my code:

clear
close all
clc

% Read in commands from text file
filename = input('Example2.txt');

fileID = fopen(filename,'r');
Dir = fscanf(fileID,'%f');
fclose(fileID);

% Store commands in "cmd" matrix
for i = 5:5:length(Dir)
    for j = 1:1:5
        cmd((i/5),j) = Dir(i+j-5,1);
    end
end
cmd(:,3:4) = cmd(:,3:4) ./ 100;

Here is what the g-code file looks like:

1 1 0295 0000 000
2 1 0295 0000 365
1 4 0495 0000 000
2 4 0495 0000 365
1 4 0265 0000 000
2 4 0265 0000 365
1 4 0000 0000 000
2 4 0000 0000 185
1 3 0135 0000 000
2 3 0135 0000 365

what's this line supposed to mean?!

filename = input('Example2.txt');

Why not just this:

fileID = fopen('Example2.txt', 'r');

Btw, readmatrix makes life a lot easier:

fileContent = readmatrix('Example2.txt');

Thanks Ive J, that helps!

Err in the code:

filename = 'Example2.txt';  % Corrected ONE. No input() that creates the error
