How can I break a WHILE or a FOR loop in Simulink?

I want to break a for loop or a while loop in Simulink. For instance, we have break statement in C. How do I do the same in Simulink?

Hi Snehal,

To achieve break functionality within 'while' loops in Simulink, the 'While Iterator' block can be utilized in conjunction with other blocks to replicate the effect of a 'break' statement. Refer to the following thread for an implementation example:

Regarding 'for' loops, Simulink does not inherently support breaking out of a ‘for’ loop using the 'For Iterator' block. However, a workaround can be implemented as detailed in the provided thread:

Refer to Simulink Documentation for more information about ‘While Iterator’ and ‘For Iterator’ blocks.
