for i = 1:3
x{i} = rand(3,3);
end
How can you display a number say in matrix x{1} ,i want to get the number of row 2,column 3 and how can we make a comparison between matrix x{1} element and x{2} element???

you have access to cell entries e.g. by using x{1}(2,3); if your matrices have all the same size i would suggest saving them in an array using
x(:,:,i)= rand(3,3);
in your loop, then it is easily accessible by using conventional triple indexing. x{1}(2,3) would then be x(2,3,1)

it depends a bit on which element you want to comapre and how you want to compare them. if you want to compare the elements at posiiton x=3 and y =2 using a histogram you could call e.g. histogram(x(2,3,:))

x=rand(5,3);
for i=1:5
for j=1:3
A(i,j)=x(i,j);
end
end
this is for creating one single matrix. i want to create more than 1 matrix say 6 matrices. all the values will be using rand function.So how to create??? using x(:,:,i)=rand(3,3) i got it but when we actually want to compare elements between two matrices , how will we do???
