Write a function max_sum that takes v a row vector of numbers & n,a positive integer as inputs.The function needs to find n consecutive elements of v whose sum is largest possible.It returns summa & index of first element of n consecutive integers.
You can get a speedup by using a convolution to calculate the moving sum: v=randi(100,2000,1); n=10; clc timeit(@() option...

Is an infinite for loop infinite?
The for-loop will run for int64(inf) iterations. If you want an actual unending loop, consider using while true.

You will have to store the handle to your last plotted graph and either delete it, or set the Visibility to 'off'.
