Modify a cell array referring to another cell array

Given the following code

G= {[1 2 1 2 1 2 3 4 5 4 5 4 6 3 9 3 9; 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85],[1 1 1 1 2 3 4 4 4 5 4 6 3 6 3 9; 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 ]};
SP= [1 2 3 4 5 6 9]; 
t1 = 20; t2 = 20 ; t3 = 20 ; t4 = 20 ; t5 = 20 ; t6 = 20 ; t7 = 20; t8=20 ; t9=20;
for i = 1:size (G,2)
result = cell(size(G));
for gidx = 1:numel(G)
    [uval, loc1, ids]  = unique(G{gidx}(1, :));
    count = accumarray(ids, 1)';
    result{gidx} = arrayfun(@(v, s, n) [repelem(v, n); s, zeros(1, n-1)], uval, G{gidx}(2, loc1), count, 'UniformOutput', false);
end
    AB = G{i}(1,:);
end 

With the value contained in the fist raw of each cell G, I want to modify the arrays contained in cell "result"

I for example we take the first raw of the first cell of G, reported as AB in each cycle:

1 2 1 2 1 2 3 4 5 4 5 4 6 3 9 3 9

at each iteration everytime I meet a specified element, I want to modify its array in result.

In particular, if I consider result{1, 1}{1, 1}" that was

1 1 1

5 0 0

Should now become

1 1 1

5+t1 5+t1+t1 5+t1+t1+t1

so

1 1 1

25 45 65

That is: every time I meet 1 in AB, I want to modify the values inside "result" that refer to that element and add everytime the value t1 to the previous one.

For element 2, at the beginning the result was

2 2 2

10 0 0

Then has to become

2 2 2

10+t2 10+t2+t2 10+t2+t2+t2

...

For element 9, at the beginning the result was

9 9

75 0

Then has to become

9 9

75+t9 75+t9+t9

I hope that it's clear what I would like to obtain

May someone help me with this task?

The code in your question does not have a t9. Does t8 and t9 both equal 20?

Do you really need separate variables for t1,t2... tn? Can we just use a vector t and use indexing such as t(n)?

Sorry, I've modified it now.

And yes we can use indexing!

[Adam Danz]

The last example breaks your pattern. I think the last example should be

For element 9, at the beginning the result was
9	9	
75	0	
Then has to become
9	9	      
75+t9	75+t9+t9

yes !

Replace your t1,t2, t3... with this

tt = [20 20 20 20 20 20 20 20 20]; %Much easier to work with 

Then replace the result{} line in the for(gidx...) loop with this

result{gidx} = arrayfun(@(v, s, n, t) [repelem(v, n); s + t.*(1:n)], uval, G{gidx}(2, loc1), count, tt(uval), 'UniformOutput', false);
