Hi all, I am trying to write a script that creates a larger matrix B from a smaller matrix A = [1;1;1;2;2;2;3;3;3;4;4;4] whereby A is copied into B in N times. E.g if N = 4, B = [1;1;1;2;2;2;3;3;3;4;4;4;1;1;1;2;2;2;3;3;3;4;4;4;1;1;1;2;2;2;3;3;3;4;4;4;1;1;1;2;2;2;3;3;3;4;4;4]. Thank you for your help in advance.

>> A = [1,2,3,4];
>> B = repmat(A(:),4,1)
B =

>> BB = repmat({A},4,4);
If a cell contains an array with more than one element, then it shows a summary of that array:
>> X = {5}
X =
[5]
>> X = {5:6}
X =
[1x2 double]
but the data is still all there!:
>> X{1}
ans = 5 6
