I've the following code

function fun(i)
persistent ss
persistent s
s = vercat(s,rand(1,2))
if i== 4
    ss(j) =  s ;
    % here I want to clear the persistent variable s
end
end

The above function is executed in the following manner

for j = 1:4 
for i = 1:4
i
fun(i)
end
end

I would like to ask for suggestions on how to clear the persistent variable s when i = 4.

Hello Deepa Maheshvare,

According to documentation persistent variables can be cleared by clearing the function from memory. If you want to reset the value of the variable within the function just assign a new value (which could be [] as well).

Kind regards,

Robert
