I have the following sizes of arrays of doubles:
dev 101x1
HessW 4x4x101
The code in question:
Hess=zeros(4);
for i=1:101
for j=1:4
for k=1:4
Hess(j,k) = Hess(j,k) + 2*(HessW(j,k,i)*dev(i) + GradW(j,i)*GradW(k,i));
% Incorrect original line:
%Hess(j,k,i) = Hess(j,k,i) + 2*(HessW(j,k,i)*dev(i) + GradW(j,i)*GradW(k,i));
end
end
end
Thanks.

Fake data:
dev = rand(101,1);
HessW = rand(4,4,101);
A = zeros(4,4,101);
for i=1:101
for j=1:4
for k=1:4
A(j,k,i) = A(j,k,i) + 2*(HessW(j,k,i)*dev(i) + GradW(j,i)*GradW(k,i));
end % ^^^^^^^^ this contributes nothing
end
end
