Use nested loops and formatted print statements to reproduce the following printed table of numbers.

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9 10

My current code is this:

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

   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10
   1 2 3 4 5 6 7 8 9 10

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.
