Comparing two arrays +

Hi I am trying to compare two arrays and apply different mathematical operations here...

a = [10 20 30 40];
b = [20 30 30 10];

I want to compare first index of two arrays and if the first index of first array is bigger than the second array one, take the first value and return it

If its not, take an average of two and return.

So it will return this...

c = [15 25 30 40];

Could you help me with finding this?

What have you done so far? What specific problems are you having with your code? Have you been instructed to use for-loops or can you use any MATLAB functions?

clc
clear all
a=[10 20 30 40];
b=[20 30 30 10];
for i=1:length(a)
    if a(i)>=b(i)
        c(i)=a(i);
    else
        c(i)=(a(i)+b(i))/2;
    end
end
c

% This will work perfectly untill both a and b are of same length. please provide a up thumb if this helps to you.
% Thank you.
