i hava two matrix 2x8

A=2*ones(2,8)
B=3*ones(2,8) 

what i need is to access on

1) on each column of matrix A so i need to get out a column vector 2x1 for 8 times to use it in a certain iteration

2) and then on each column of matrix B the same

all of this in the same iteration inside a loop

because if the two matrix are 1x8 it will be easy with two for i=1:8 and j=1:8 (in this case he gave me (1,1) and (1,2) ............ 1,8) then (2,1) ,(2,2) ................. (2,8)) but in this case i need to extract not an element but a column vector.

thank you

Example would be good. Plus explain what "access on" means. Do you simple mean

[rows, columns] = size(A);
for col = 1 : columns
    thisColA = A(:, col) % Extract column from A.
    thisColB = B(:, col) % Extract column from B.
    % Now do something .....
end

clear all

clc

A=2*ones(2,8)

B=3*ones(2,8)

for i=1:2

for j=1:8

end

i want to creat a matrix C 2x1 that the

1) first elementi is a matrix that contain A (2x8)

2) second element is a matrix that contain B(2x8)

thank u

No loops needed:

C=permute(reshape([A;B].',size(A,2),size(A,1),[]),[2,1,3]) % C(:,:,1) contains A and 2 B
