break terminates the execution of a for or while loop. Statements in the loop after the break statement do not execute. In nested loops, break exits only from the loop in which it occurs. Control passes to the statement that follows the end of that loop.
I found some newsgroup postings from about 4 years ago and back then there was no way to terminate a script from running in a infinite FOR loop without using ctrl+alt+delete.
You can programmatically exit a loop using a break statement, or skip to the next iteration of a loop using a continue statement. For example, count the number of lines in the help for the magic function (that is, all comment lines until a blank line): fid = fopen('magic.m','r'); count = 0; while ~feof(fid) line = fgetl(fid); if isempty(line) break
21 maj 2014 · I have a while loop, infinite, and I want to stop it when I press a keyboard key. Pseudocode: While(1) do stuff; listening for key; if key is pressed break; end end
MATLAB lets you end the execution of a for or while loop if specific conditions are met. In this video, learn how to use the break keyword to stop executing a loop.
Terminating a Loop Prematurely: Break and Continue. As you may recall, a while loop will evaluate all its statements without checking the condition. Similarly a for loop will run through all of its iterations. The break keyword tells MATLAB® to exit the loop immediately.
The syntax of a while loop in MATLAB is −. <statements>. The while loop repeatedly executes program statement (s) as long as the expression remains true. An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Otherwise, the expression is false.
