how to find average values of answers

%For example, if you write this code for a=1:5; b = 2*a + 1 end the answers are >> b =

     3

b =

     5

b =

     7

b =

     9

b =

    11
I want to calculate the mean values for these answers 
b average = (3 + 5+ 7+ 9+11) / 5 = 7

Answer 1

[Purushottama Rao]

b=zeros(1,5)
for a=1:5
b(a)=2*a+1;
end
k=mean(b);

If you want to diplay every time avg, move mean commnd inside the for loop

ok thanks, but ur code will give vector answer for each value of b
