My current code is this:

    for j=1:10
        fprintf( '%5d',j);
    end
    fprintf('\n');
end;

You’re almost there. You have to set the upper limit of your ‘j’ loop to be the current value of ‘i’:
for i=1:10;
    for j=1:i
        fprintf( '%5d',j);
    end
    fprintf('\n');
end;
By the way, it is generally not a good idea to use ‘i’ and ‘j’ as variables, including loop counters. MATLAB uses them for its imaginary operators, and using them as variables can cause confusion in those instances.
