Compile a simple function

Hi everyone, I'm a very young user of Matlab and completely new to the programming world. I'm trying to do a simple matlab program that ables me to calculate a simple Mathematical equation ( Newton's Law F=m.a).

I've done this simple code:

function F = Newton(m, a)
F=m*a
end

So, if I in Matlab type:

x=Newton(2,2) I get the result correctly.

So I tried to compile this simple .m file with the help of deploytool. But when I finish to create the .exe file, when I click on it nothing happens.

And, if I go to that .exe file through DOS line command, I can see that the error I get is:

Error using newton (line2) Not enough input arguments. MATLAB:minrhs

So, I need your help. I'm very new to this so I'm sorry if it is a stupid question.

Thanks to all that will try to help me

Regards

when you compile only the function, how are you going to call this function? I think you should create a script with, for example inputdlg to introduce your data and msgbox or gui to display your result

I see.. So the problem is that I need some kind of dialog for the program know things right?

Is there any example I can see how this system works?

Thank you for your answer

Example

a=inputdlg('enter a');
a=str2double(a);
y=sin(a)
msgbox(['the result is' num2str(a)])

[ropbasuel]

Thank you for your example! Can you tell me what is wrong in this?

inputdlg ('enter a')

a=str2double(a);

inputdlg('enter m')

m=str2double(m);

F = m*a;

msgbox(['The result is' num2str(F)])

I get this error:

Undefined function or variable 'a'.

Error in newton (line 2) a=str2double(a);

Thanks

it's

a=inputdlg ('enter a')

[ropbasuel]

Oh.. Now it works! Thank you for the help. Can I make only one more question?

Instead of having 2 steps in asking the variables, can I ask both variables at the same time? Like making a dialog with two different blank cases for me to put the values of "m" and "a" at the same time!

Thanks

x=inputdlg({'enter a','enter b'})
a=x{1}
b=x{2}

Thank you Azzi! I really appreciate your help!

Thanks for your time!
