IF loop end if

FOR loop that runs i=1:N with an embedded IF loop that executes if val(i)>0 and val(i+1)<0 or opposite way around and outputs i. This works fine, but does take time.

How can I stop the FOR loop from continuing to run once it finds this value of i? What takes most running time is that it goes through the whole FOR loop range even if it finds the sign change early on.

use break after you get the desired value. It will take you out of the for loop

[James]

Will that not just end the IF loop rather than the outer FOR loop?

[David Sanchez]

break only works with while and for loops, it has no effect on if conditions.

[David Sanchez]

break will terminate the closest for/_while_ loop.
