break (MATLAB Function Reference)

Terminate execution of a for loop or while loop

Syntax

break

Description

break

terminates the execution of a for loop or while loop. In nested loops, break exits from the innermost loop only.

Examples

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)
