Hi

I have written a code in a live editor and I want to make a while loop that whenever I run the code it starts from the begining and goes to the end and then goes back to the beginning of the code and run the whole code again and again continuosly until I break out the loop.

Can you please assist.

Cheers

In the test I just did in R2020b, I created a very simple infinite while loop. The output for the first 10 disp() showed up, with the rest not being shown on the right (which is default in live script, the output is kept in a scrollable window.) When I clicked the Stop button, my MATLAB crashed. Repeatably.

Mathworks says that the crash I mentioned above was a problem for R2020b, and has been fixed for R2021a. They said that the problem occurs when using disp() in a loop in Live Script, but does not occur if you just let MATLAB display the value by naming the variable without disp()

As per my understanding of your query you need to execute your live script multiple times using a while loop. Here is a simple walk around using a while loop.

while 1
fprintf("Test1")

fprintf("Test2")

fprintf("Test3")
end

You may simply add a while 1 in the start for initializing an infinite loop and end to finish the while loop. You may even change the expression to fix the number of iterations as per requirement and for breaking you may use if statement along with break, or pressing Stop in the editor, or this way: https://www.mathworks.com/matlabcentral/answers/308386-create-keyboard-listener-to-interrupt-a-running-function
