for i = 1:5
  i
  clear
  i
end


i = 1
ans =  0 + 1i
i = 2
ans =  0 + 1i
i = 3
ans =  0 + 1i
i = 4
ans =  0 + 1i
i = 5
ans =  0 + 1i


The loop executes 5 times with no error.

What wizardry is this? How did i get its loop value back after being cleared?

Refactor the variable name and it causes an error.


for a = 1:5
  a
  clear
  a
end

gives

a = 1
error: 'a' undefined near line 1, column 24


Now the loop executes only once and ends with an error.
