Split string into string based on character type

Hello,

I have variable data that looks like this: 1A2 and is formatted number+letter(s)+number. I'd like to split this string to mentioned 3 types. Both numbers can be 2-digits. How can I do this?

I tried strtok and split but with no success. Thank you.

>> S = '1A2';
>> C = regexp(S,'(\d+)(\D+)(\d+)','tokens','once')
C = 
    '1'    'A'    '2'

I think I found solution. I'm only missing how to extract first number.

string="1AA12";
check=isletter(string);
letter=string(check);
number2=strtok(string,letter);
