I have a function

function result=add()
    a=input('what is the first number:');
    b=input('what is the second number:');
    result=a+b;

Now I want to create a separate script that puts the asked values 'a' and 'b' automatically in function.

I want to add 3 and 5. I tried this but failed.

add;
3;
5;

Does someone has a solution?

You would have to define a function that takes two arguments (or an array of inputs to add), e.g. for an example of a fixed two arguments:

function result = add( a, b )
if ~exist( 'a', 'var' )
   a=input('what is the first number:');
end
if ~exist( 'b', 'var' )
   b=input('what is the second number:');
end
result = a + b;

Then you can call it as any of the following

add
add( 3 )
add( 3, 5 )

Also don't use 'sum' as a variable name, it is a function name and shouldn't be overwritten even if you are using your add function rather than the builtin sum function.

I just want to create a saperate script from function, that automatically put the asked values in variables one after another. I don't want to call a function by inputs as you written.
