varargout-varargin commands for easy calculation

Hello everyone,

I believe that my question is not hard...

I have this code

function  [varargout] = trg (varargin) 

A1=varargin(1,1)

A2=varargin(1,2)

A3=varargin(1,3)

a=input('Value= ')

varargout=[(A2{:}-A1{:})*a+A1{:},A3{:}-(A3{:}-A2{:})*a]

end

this code can provide for a=0;

[

k]=trg(1,2,3)

a=0

k=
   1 3

I want to have as inputs for example [1 2 3] [0 2.5 5] and as outputs lets say [k p] or more inputs and outputs

For example if

[k p]=tgr([1 2 3],[0 2.5 5]) and for a=0; The desirable results should be

k =
    1 3

p =
    0 5

A1 must take the first number of [1 2 3] A2 the second and A3 the third and the same to [0 2.5 5] and for more inputs.

Nik - rather than using a variable number of inputs (and so outputs), why don't you just have a single input parameter that is an nx3 array. Your output would then be a nx2 array. For example,

 function  [dataOut] = trg (dataIn) 

 n = size(dataIn,1);
 dataOut = zeros(n,2);
 for k=1:n
    A1 = dataIn(k,1);
    A2 = dataIn(k,2);
    A3 = dataIn(k,3);
    a=input('Value= ');
    dataOut(k,:) = [(A2-A1)*a+A1,A3-(A3-A2)*a];
 end

If you then call the above as

 >> trg([1 2 3;0 2.5 5])

 ans =
     1     3
     0     5

you get the expected answer.
