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');

Oh okay, so it's not the commas at all its the square brackets doing the concatenating. Well I've learnt lots today lol. Thanks for the help guys

Yes, I almost always use commas to separate values unless it is a pure list of non-negative numbers.
[2,-3,4,-6,7]
['This ','string ','is built from ','sub-strings.']
but only for non-negative integers
[3 4 5 6 7]
Also, note the other: [1;2;3;4;5]
