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.
