BREAK Exit Execution In Loop

Section: Flow Control

Usage

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.

Example

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
