MATLAB: Include variables in matlab user input

input

Hi guys, Basically I just want to use a variable that I've already declared when asking a user for input.
a= input('Pick a letter') b= input('Now ask something about the letter' a '? ')
Something along those lines. Even if I have to convert 'a' to another format after its found would be fine. I've looked over the internet and matlabs help for input a fair bit but can't find anything. Does anyone know if this is possible? Thanks in advance Josh

Is this what you are after?
a = input('Pick a letter: ','s');
b = input(['Now ask something about the letter ', a, '? '],'s');
