Hello,
Here is what i tried based on my understanding of your question.
Hope it does help you.
x=99;y=99; %choose your constants x and y.
A=rand(100); % A and B are 100x100 arrays, you can also define them as 1x100 arrays.
B=rand(100);
C = {A,B}; % C is a 1x2 cell array
C{1}
C{1}(:,2:2:size(C{1},2)-mod(size(C{1},2),2))=C{1}(:,2:2:size(C{1},2)-mod(size(C{1},2),2))+x;
C{1}
C{2}
C{2}(:,1:2:size(C{1},2)-(~mod(size(C{1},2),2)))=C{2}(:,1:2:size(C{1},2)-(~mod(size(C{1},2),2)))+y;
C{2}
