How can I put this in a simpler form?
Area=(y(1)+y(2)/2+(y(2)+y(3)/2+(y(3)+y(4)/2+(y(4)+y(5))/2

n = length(y);
Area = 0;
for k=1:(n-1)
Area = Area + (y(k) +y(k+1))/2;
end

y = randi(10,5,1);
Area = sum(conv2(y,[1;1]/2,'valid'));

By using indexing and simple maths (y1 + y2)/2 = (y2 - y1)/2 + y1 therefore, you can do this as
Area = diff(y)/2 + y(1, end - 1)
