Combine 2 char vectors

Hi everyone, Here are two vectors :

A='IMDOINGATEST'
B='ABCDE'

I would like to get this : (a regular mix)

C='IAMBDCODIENAGBACTDEESATB'

Note that A can be smaller than B but A won't repeat in B. Only B repeats in A.

Thank you !

This will mix them as described in question

C = repmat(' ', 1, 2*numel(A))
C(1:2:end) = A;
C(2:2:end) = [repmat(B, 1, floor(numel(A)/numel(B))) B(1:rem(numel(A), numel(B)))];

For example,

A='IMDOINGATEST'
B='ABCDE'

will produce

C =
  'IAMBDCODIENAGBACTDEESATB'

and

A='IMDO'
B='ABCDE'

will mix to form

C = 
  'IAMBDCOD'  % no repetition of A

I will try this tomorrow, thank you for the answer !

You are welcome.

A slightly different approach:

>> A = 'IMDOINGATEST';
>> B = 'ABCDE';
>> C = repmat(B,1,ceil(numel(A)/numel(B)));
>> C = reshape([A;C(1:numel(A))],1,[])
C = IAMBDCODIENAGBACTDEESATB

Or

>> A = 'IMDO';
>> B = 'ABCDE';
>> C = repmat(B,1,ceil(numel(A)/numel(B)));
>> C = reshape([A;C(1:numel(A))],1,[])
C = IAMBDCOD
