for i=1:10
if randi(10)==3
i=i-1;
end
end
In the above code, i must get reduced by 1 whenever the if condition comes true. But it doesn't gets so. Any modifications so that loop variable i gets modified inside the loop body?

This does not work in a for loop, but in while:
i = 1;
while i <= 10
disp(i)
...
i = i + 1;
if randi(10) == 3
i = i-1; % Or i - 2?
end
end
