You could create a cell array of strings:

C = {'A1','A31','A61','A91'}

Or if you have R2016b or newer, then you could use strings:

S = string({'A1','A31','A61','A91'})

Sorry,,, my question was incomplete... I have one string array [A B C D ...]

I have another numeric vector, say B = [1:2:20]

I want to create a alphanumeric array as per following result

A1 A3 A5 A7.... B1 B3 B5 B7 C1 C3 C5 C7....

If you have R2016b or newer then use strings (untested):

 B = 1:2:20;
 S = string({'A','B','C','D'});
 S+B(:)

For older version you could do something like this:

>> B = 1:2:20;
>> C = {'A','B','C','D'};
>> N = arrayfun(@num2str,B(:),'Uni',0);
>> Z = strcat(repmat(C,numel(B),1),repmat(N,1,numel(C)));
>> Z = Z(:)'
Z = 
  Columns 1 through 15
    'A1'    'A3'    'A5'    'A7'    'A9'    'A11'    'A13'    'A15'    'A17'    'A19'    'B1'    'B3'    'B5'    'B7'    'B9'
  Columns 16 through 30
    'B11'    'B13'    'B15'    'B17'    'B19'    'C1'    'C3'    'C5'    'C7'    'C9'    'C11'    'C13'    'C15'    'C17'    'C19'
  Columns 31 through 40
