Hi!
I have a n x m cell array and i want to add a multiple of a constant as n and m increases.
(1,1) (1,2) (1,3)
(2,1) (2,2) (2,3) ---- add constant to row nr 2.
(3,1) (3,2) (3,3) ---- add constant x2 to row nr 3.
I would also like to add a constant to columns as they increase.
Any suggestions?

Yes I understand your question but, just to blear could you tell as the matrix increases each time,
a constant is added to 2nd row and a multiple of that to the 3rd row, and another constant to 1st column and a multiple of that to the 3rd column
OR
a constant is added to 2nd row and a multiple of that to the last row, and another constant to 1st column and a multiple of that to the last column
And, is the the multiplication of the constant is same for each time?

Hi Holmbrero,
I understand that you wish to add multiples of constants to each row. I am providing with a pseudo-code to help you do that -
for i=1:size(c,1)
for j=1:size(c,2)
c{i,j} = c{i,j} + constant * i
end
end
Assuming that 'c' is your cell array, the above code would add each cell element with a constant, depending on the row number.
You can similarly replicate the code to add each element with constant, depending on column number, like this -
for i=1:size(c,1)
for j=1:size(c,2)
c{i,j} = c{i,j} + constant * j
end
end

Hi!
I solved it by creating two new matrices with the added constants and then simply added these to the cell array.
The problem was somehow sort of hard to describe but i think your solution is also appliciable.
