So I was recently posed with the question, what is the difference between a while true loop and a for i = 1:Inf loop. I have done quite a bit of research, but I cannot seem to come up with an answer. Do you know?
No products are associated with this question.
The for-loop provide the loop-variable, ii. Why, is that interesting?
In addition to what Per Isakson has written, I would add that the loop variable, after a certain point, will lose precision and become ill-defined. I think MATLAB will try to gracefully provide a value for ii, but after a point the successive ii's will be equal to each other until the background rounding scheme clocks it over into the next representable value. (As I recall, there was a previous similar thread some time ago that explored this topic)
k=0; while rand<0.8 k=k+1; end
The while loop will run until a condition rand < 0.8 is false, we don't know when it occurs, because rand is a random number. In this case we can't use a for loop
