disp('This program convert Celsius to Fahrenheit');
val = input('Type 1 for Celcius to Farenheit and Type 2 for vice versa: ');
switch val
case 1
Celsius=input('Write a temperature in Celsius and you''ll have the result in Fahrenheit: ');
disp([ 'x = ' num2str(Celsius) ' Celcius and y = ' num2str(Celsius*1.8+32) ' Fahrenheit']);
case 2
Faren=input('Write a temperature in Farenheit and you''ll have the result in Celcius: ');
disp([ 'x = ' num2str(Faren) ' Fahrenheit and y = ' num2str((Faren-32)/1.8) ' Celcius ' ]);
end

What do you want exactly? I think you don't need an anonymous function for this simple script

An explanation of this odd request is indeed needed. Why does it need to be an anonymous function? Why can't it be a normal function or a local function or a nested function?
Bearing in mind that strictly speaking, it's impossible to convert this script into an anonymous function since anonymous functions in matlab can only consist of a single non-branching, non-assigning statement.

Hi Jaeyoung, as Alex said you probably don't need anonymous function for this script and it won't make the code much shorter. But you can use this one below.
disp('Type 1 for Celcius to Fahrenheit, Type 2 for vice versa');
x = inputdlg({'Celcius or Fahrenheit','Temperature'},...
'Converter',[1 60; 1 35]);
converter = {@(celcius) num2str(celcius*1.8+32);
@(fahren) num2str((fahren-32)/1.8);
};
converter{str2num(x{1})}(str2num(x{2}))
