Adding two vectors of different classes

Hi I am trying to add to vectors of different classes:

a = [13 13 14 15 14 15 13 14 15];   %double
b = 'ABAABBAAB';    %char

I want to return this

c = '13A 13B 14A 15A 14B 15B 13A 14A 15B';  %string

a = [13 13 14 15 14 15 13 14 15];   %double
b = 'ABAABBAAB';    %char

b = num2cell(b) ; 
a = strsplit(num2str(a)) ; 

iwant = strcat(a,b)
