Matrix manipulation problem under MATLAB

hello I have two matrix the first Swapping={1,1,1; 1,5,1; 2,3,4};

and the second C1={59,57,46 4,39,35 8,22,20} I want to display in a third matrix the values of the second matrix that have the same box with the valeus 1 and 0 besides

result matrix={{59,57,46 4,0,35 0,0,0}

Storing scalar numerics in cell arrays will make your processing pointlessly complex, so I will presume that you actually sensibly store your numeric data in simpler and more efficient numeric arrays. Then your task is easy:

>> Swapping = [1,1,1;1,5,1;2,3,4]
Swapping =
   1   1   1
   1   5   1
   2   3   4

>> C1 = [59,57,46;4,39,35;8,22,20]
C1 =
   59   57   46
    4   39   35
    8   22   20

>> result = C1 .* (Swapping==1)
result =
   59   57   46
    4    0   35
    0    0    0
