adding zeros to empty spaces of an array

Assuming you have the following (note: the numbers are irrelevant...it's the process I need to understand)

A = [ 1 4 7 8 12]

B = [3 5 10]

and you want to match the two as 1 even though they are uneven as follows, but you want to match the remaining values with zeros (as follows:)

[3,1] (1 from A and 3 from B)

[7,5] (7 from A and 5 from B)

[12,10] (12 from A and 10 from B)

while the remaining unmatched numbers in A you want as follows

[4, 0] (4 in A matched with 0)

[8,0] (8 in A matched with 0)

Note: the 0's will be added to the B to make it the same size as A

PLEASE HOW WOULD YOU GO ABOUT THIS.....APPRECIATE ANY HELP

[Sruthi Gundeti]

I am able to get output C =[ 3 0 5 0 10] with the following code . I used setdiff function which is same as difference function in sets

A = [ 1 4 7 8 12]

B = [3 5 10]

C=B(1)

for i=2:length(A)

if mod(i,2)==0

C(i)=0

end

C=[C setdiff(B,C)]

end
