break

The break statement terminates the execution of a for loop or while loop. When a break statement is encountered, execution continues with the next statement outside of the loop. In nested loops, break exits from the innermost loop only.

The example below shows a while loop that reads the contents of the file fft.m into a MATLAB character array. A break statement is used to exit the while loop when the first empty line is encountered. The resulting character array contains the M-file help for the fft program.

• fid = fopen('fft.m','r');
  s = '';
  while ~feof(fid) 
     line = fgetl(fid);
     if isempty(line)
        break
     end
     s = strvcat(s,line);
  end
  disp(s)
  

continue
