loop array without index in matlab

In MATLAB, you can loop over an array without using an index by directly iterating over its elements using the for loop. Here is an example:

main.m
arr = [1, 2, 3, 4, 5];
for value = arr
  disp(value);
end
58 chars
5 lines

In the above code, we initialize arr and then loop over its values using the for loop. In each iteration of the loop, the current element of the loop is stored in the value variable, which we then display using the disp function.

The output of the above code should be:

main.m
1
2
3
4
5
10 chars
6 lines

Note that this method only works for iterating over the values in the array. If you need to access the index of each element, you would need to use a traditional for loop with a loop variable that represents the index.
