Hi,
I have an array of values and I need to frame an expression such that it chooses the value from the array automatically instead of me assigning a value from the array everytime. For example, if
A=[1 2 3 4]
B=[5 6 7 8]
while initialising A, B for the first time I choose A=2, and B=6 (A and B are selected with corresponding element) and next time A=4, B=8
Could someone please give some suggestions.

The function
choose=@(arr) arr(ceil(rand*length(arr)))
chooses a random element of a vector. For example
choose([1 2 pi 8 i])

Thanks for your reply. Could you please replace with A and B in the equation you have mentioned. I don't get it completely.
