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.

I need to create a button UI that undo the graph which I plotted without using GUIDE
You will have to store the handle to your last plotted graph and either delete it, or set the Visibility to 'off'.
