Section: Flow Control
The break statement is used to exit a loop prematurely. It can be used inside a for loop or a while loop. The syntax for its use is
break
inside the body of the loop. The break statement forces execution to exit the loop immediately.
Here is a simple example of how break exits the loop. We have a loop that sums integers from 1 to 10, but that stops prematurely at 5 using a break. We will use a while loop.
break_ex.m
function accum = break_ex
accum = 0;
i = 1;
while (i<=10)
accum = accum + i;
if (i == 5)
break;
end
i = i + 1;
end
The function is exercised here:
--> break_ex ans = 15 --> sum(1:5) ans = 15
