Printing and Plotting after each loop

I have a for loop where the structure is like this

A=[1 3 4;3 5 6]
U=[]
for i=1:10
...
U=A
end 

how would I print U matirx after each loop on the text file beacause when I am doing that only the matirx in the 10th iteration loop prints and how would I be able to plot all those iterations in one figure using point clouds?

It seems to print all the iterations to me

A=[1 3 4;3 5 6]

A = 2×3

1 3 4 3 5 6

U=[]

U =

     []

for i=1:10
A = A * 2;
U=A
end 

U = 2×3

2 6 8 6 10 12

U = 2×3

4 12 16 12 20 24

U = 2×3

8 24 32 24 40 48

U = 2×3

16 48 64 48 80 96

U = 2×3

32 96 128 96 160 192

U = 2×3

64 192 256 192 320 384

U = 2×3

128 384 512 384 640 768

U = 2×3

256 768 1024 768 1280 1536

U = 2×3

512 1536 2048 1536 2560 3072

U = 2×3

1024 3072 4096 3072 5120 6144

Do you want it to print to a file or the command window?

I want to print it to a text file

A=[1 3 4;3 5 6]

A = 2×3

1 3 4 3 5 6

U=[]

U =

     []

for i=1:10
A = A * 2;
U=A;
dlmwrite('U.txt', U, '-append')
end

!cat U.txt

2,6,8

Thanks a lot! Do you know how to create a space between each iteration? For instance:

2,6,8

6,10,12

4,12,16

12,20,24
