Richard 2012-2-28

Is there a possibility of performing an if statement following an user input. For exampl:

Variable = input('type 1,2, or 3 :');
 Then stating that if the user typed 1...

I would like to use different values in my equations depending on the value inserted by the user, is this possible?

Yes,

Variablein = input('type 1,2,or 3:\n');
if (Variablein == 3)
disp('You typed 3');
end

For a string:

Variablein = input('type 1,2,or 3:\n','s');
Variablein = str2num(Variablein);
  if (Variablein == 3)
  disp('You typed 3');
  end

I don't understand probably, but:

Variable = input('type 1,2, or 3 :')
if Variable == 1
...
elseif Variable == 2
...
elseif Variable == 3
...
else
...
end

Or use a switch case statement.
