How to combine to identical 'for' loops with sequential varying variables ?

I have two 'for' loops:

1st loop)

a1=[1 2 3 4 5];

b1=[6 7 8 9 10];

for i=1:5

c1(i)=a1(i)+b1(i)

end

2nd loop)

a2=[4 5 7 8 9];

b2=[3 2 4 5 7];

for i=1:5;

c2(i)=a2(i)+b2(i)

end

The problem: I have to combine above mentioned two 'for' loops in a such way that in each iteration (j) loop has to work with variables corresponding to j. For example if j=5

then,

for j=5;

for i=1:5

c5(i)=a5(i)+b5(i)

end

end

I will give another example for clarification (if j=6):

for j=6;

for i=1:5

c6(i)=a6(i)+b6(i)

end

end

Numbering variables like that is completely the wrong approach and should be avoided.

One better approach is to use a container array, e.g. a cell array:

a{1} = [1,2,3,4,5];
b{1} = [6,7,8,9,10];
a{2} = [4,5,7,8,9];
b{2} = [3,2,4,5,7];
n = numel(a);
c = cell(1,n);
for ii = 1:n
    for jj = 1:5
        c{ii}(jj)=a{ii}(jj)+b{ii}(jj);
    end
end

ans = 1×5

7 9 11 13 15

ans = 1×5

7 7 11 13 16

Of course for this example the best approach would be to use numeric arrays and vectorized operations (for the given example using loops and multiple vectors is very inefficient and a very poor use of MATLAB):

a = [1,2,3,4,5;4,5,7,8,9];
b = [6,7,8,9,10;3,2,4,5,7];
c = a+b

c = 2×5

7 9 11 13 15 7 7 11 13 16

Thank you for your answer

But above mentioned for loops were just simple example, actually my 'for' loops are complicated
