Finding Maximum magnitude out of two arrays and output position with sign of that element

3 6 9 13 16 19;

2 5 8 12 15 18;

1 4 7 11 14 17]

Output :

I need to find output maximum magnitude of each element from a and b combined and extract postion of that element either from a or b array. The output looks below :

c = [-1 -4 -7 -11 -14 -17;

-2 -5 -8 -12 -15 -18;

-3 -6 -9 -13 -16 -19;

3 6 9 13 16 19;

2 5 8 12 15 18;

1 4 7 11 14 17]

Any help would be appreciated.

Thanks in advance

for i = 1:6

for j = 1:6

if (sign(a1(i,j)) == -1 && sign(b1(i,j)) == -1)

c1(i,j) = min(a1(i,j), b1(i,j));

elseif (sign(a1(i,j)) == 1 && sign(b1(i,j)) == 1)

c1(i,j) = max(a1(i,j), b1(i,j));

else

if abs(a1(i,j))> abs(b1(i,j))

c1(i,j) = a1(i,j);

else

c1(i,j) = b1(i,j);

end

end

end

end

Assuming a array as a1 and b array as b1

Any efficient code that this code would be usefull.

Thanks in advance.
