How can I apply mathematical calculation for every Elements of a Cell Array ( like in Excel)

Hi Matlab Masters, I have two following Cell Arrays (or two Excel-Tables, if necessary).

Cell Array for the Bodies

    [Body]     [Weigh]  [warranty]
    [A1]        [3.5]     [2]
    [A2]        [6.2]     [3]
    [B1]        [7.1]     [1]
    [B2]        [3,9]     [4]
    [B3]        [4.2]     [5]
    [C1]        [1.3]     [7]
    ...         ....     ...

Cell Array for the partial Objects in each Body

       [Object] [x_min] [x_max] [y_min] [y_max] [Volume]
       [A1-a1]   [5.7]   [7.3]   [8.9]   [4.3]   [5.1]
       [A1-a2]   [2.6]   [5.6]   [9.3]   [5.7]   [5.2]
       [A1-a3]   [3,6]   [7.3]   [5.3]   [7.3]   [5.8]
       [A2-a1]   [8,2]   [5.8]   [2.7]   [5.3]   [6.3]
       [A2-a2]   [8.4]   [6.3]   [8.5]   [6.3]   [9.3]
       [B1-b1]   [7.1]   [6.3]   [8.2]   [8.5]   [5.3]
       [B1-b2]   [8.9]   [8.4]   [4.5]   [6.2]   [4.5]
       [C1-c1]   [7.0]   [7.1]   [1.3]   [8.9]   [1.3]
       [C1-c2]   [6.9]   [4.8]   [3.2]   [9.2]   [3.7]
       [C1-c3]   [5.3]   [2.5]   [4.2]   [6.4]   [6.3]
        ...       ...     ...     ...     ...     ...

now I want write a program, which does the following steps to the objects automatically:

1. Calculate the weigh of each object with the forular:

Weigh_obj = Weigh_body * Volume_obj/Sume of every Volume_obj in the body

for Example Weigh_A1-a1 = Weigh_A1 * Volume_A1-a1/(Volume_A1-a1 + Volume_A1-a2 + Volume_A1-a3)

= 3.5 * 5.1 /(5.1+5.2+5.8)

2. Compare the coordination of each object with the coordination of the other objects to find out,if there is a Touch between any two objects :

For Example with two Objects Object1 and Object2:

 if    ( (x2_min <=x1_min<=x2_max)or(x2_min <=x1_max<=x2_max)
      and(y2_min <=y1_min<=y2_max)or(y2_min <=y1_max<=y2_max) )

    returns '1' in corresponding positions in the matrix of n objects , like this:  
[ X]  [O1] [O2] [O3] ... [On]
[O1]  [X]  [1]  [ ]  ... ...
[O2]  [1]  [X]  [ ]  ... ...
[O3]  [ ]  [ ]  [X]  ... ...
...   ...  ...  ...  [X]
[On]  ...  ...  ...  ... [X]       
 else
     returns '0' in the corresponding Positions in the matrix
 end

so that in the end I get a full filled Object-matrix

I hope so, that I have explained my problem not so bad. 1000 Thanks for your concern !
