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 =
