MATLAB: Turning a Character input into a integer.

character to integer help str2num inputMATLAB

okay so, first of all thanks for helping, second of all im very new to matlab so please bare with me if my terminology is incorrect/my coding is incorrect.
so…
what i want to achieve is for the user to input a character when prompted, and from that stage turn it into a integer, here's what i have so far, i thought this would work ive had a play with other alternatives but really have hit a loose end so have come here to seek advice? thank you in advance for any feedback you guys give! its much appreciated. Heres's what i have made so far..
    disp('Text will go here...??:')
  input('Type here...','s') 
  UserIn = ans;
  if  UserIn == A;
    A = str2num('1')
  elseif  UserIn == B;
        B = str2num('2')
  else
  end
Just to add, the error i get it..
Undefined function or variable 'A'.
Error in CharToBin (line 38) if UserIn == A;

Best Answer

if UserIn == 'A'
However, the user might have entered multiple characters, so you should use strcmp()
if strcmp(UserIn, 'A')
