How can I create this matrix ?

Let I have three matrix

A=26X5

B=26Xj

c=26Xj

where A matrix size is fixed but in B and C the column number can be varied .I want to find a new set of matrix where the matrices number will depending on the j value .If I take j value is 4 then I will get 4 set of matrix like X(j).So how I can get it in a loop?

As example

X1=[A B(:,1) C(:,1)];

X2=[A B(:,2) C(:,2)];

X3=[A B(:,3) C(:,3)];

X4=[A B(:,4) C(:,4)];

[Chunru]

A=rand(26, 5);
B=rand(26, 7);
C=rand(26, 8);
for i=1:4
    X{i} = [A, B(:,i) C(:,i)];
end
X

X = 1×4 cell array
    {26×7 double}    {26×7 double}    {26×7 double}    {26×7 double}
