So here it's the thing. I have three cells, each one with a data of 120 values (1x120 double) and i need to compare the 1st value of the first cell with the 1st one of the second cell and the 1st one of the third cell, then the 2nd one of the first cell with the 1st one of the second cell with the 2nd one of the third cell and so on until i compare the 120 numbers of the three cells. Any ideas? Thanks in advance! Have a good day!

Can you expand on your 'comparing;. Are you comparing equality? or whichever is greater or smaller? or if the (value1-value2)<tolerance?

Assuming you wish to find the maximum of the corresponding elements in each cell
cell1={rand(1,120)};
cell2={rand(1,120)};
cell3={rand(1,120)};
foo=cellfun(@max, cell,cell2,'UniformOutput',false);
final=cellfun(@max,foo,ceff3,'UniformOutput',false)
hope this helps

Almost there mate. Let me try to make an example for you
y1=[1 %120 numbers
-1
-1
1]
y2= [-1 %120 numbers
1
-1
-1]
y3=[-1 %120 numbers
-1
1
-1]
So the final answer would be
x= [1 %The positive value indicates where the x must belong
2
3
1]

@Lucas: Your variables are not cells, but double vectors. This detail matters.

y1 = [ 1; -1; -1; 1];
y2 = [-1; 1; -1; -1];
y3 = [-1; -1; 1; -1];
[ignore, index] = max([y1, y2, y3], [], 2);
Now index contains the wanted result. If the variables are really cells:
[ignore, index] = max([y1{1}, y2{1}, y3{1}], [], 2);
