MATLAB: Vector programming of sum (greek sigma)

Question

I have this code:

I want to do it in vectorised programming but I cannot get it to run:

%generate the two random matrices with different height
h1 = 'h1';
disp('enter a number for h1, which is the height of the random matrix')
h1 = input(h1);
A = rand(h1, 200);
%method one
timer1 = tic;
the_sum=0;
for h=1:h1
    for w=1:200
       the_sum=the_sum+A(h, w);
    end
end
toc(timer1)
%method two
timer2 = tic;
h=1:h1,w=1:200;
the_sum2=the_sum2A(h, w)
toc(timer2);
thesum

Thanks for any help

Answer 1

It looks as though this is what was meant:

 %method two
 timer2 = tic;
 the_sum2 = sum(sum(A,2),1);
 toc(timer2);
