How to use matlab to achieve multiple cycles, as shown in Figure 1

Answer 1

[Walter Roberson]

ivals = 1:3;
jvals = 1:3;
numi = numel(ivals) ;
for idx = 1:numi
  i = ivals(idx) ;
  j = jvals(idx) ;
  disp([i, j])
end

Answer 2

[Steven Lord]

Another approach would be to take advantage of the fact that a for loop in MATLAB can iterate over columns of an array.

for ij = [1 2 3; 1 2 3]
    disp(ij.')
end

     1     1

     2     2

     3     3
