How to build a vector in MATLAB

Hello all, I am trying to build a vector of size 404 by 1 which is a vector of labels.

I had made the following code:

Labels = 16; r = 6;
C1 = 1:Labels;
C_labels_train = (repelem(C1,r))';
C_labels_test = [C_labels_train; C_labels_train; C_labels_train; C_labels_train ];

Here C_labels_train consists of labels of training data and I want to give such labels to test data as well.

So, my query is that C_labels_test (which are the labels of test data) has dimension of 384 by 1. So how to obtain the vector of 404 by 1 dimension ?

Any help in this regard will be highly appreciated.

Labels = 16; r = 6;
C1 = 1:Labels

C1 = 1×16

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

C_labels_train = (repelem(C1,r))'

C_labels_train = 96×1

1 1 1 1 1 1 2 2 2 2

C_labels_test = [C_labels_train; C_labels_train; C_labels_train; C_labels_train; C_labels_train(1:20) ];

C_labels_test = 404×1

1 1 1 1 1 1 2 2 2 2

one option is add the array

% add 20 elements of C_labels_train vector 
C_labels_train(1:20) % since the final vector length you want is 404 x 1 

to the final vector

C_labels_test = [C_labels_train; C_labels_train; C_labels_train; C_labels_train; C_labels_train(1:20) ];
