Varagin function with a vector

Hi, can someone help me, i must implement a matlab function with varargin and the input and the output arguments must be a vector. Which brackets should i choose to implement a vector in a varagin function The code below should show, how i would try to convert the temperature from celsius to fahrenheid. Thanks for your help

function [ output ] = c2f(varargin) %UNTITLED Summary of this function goes here % Detailed explanation goes here

f=convtemp([nargin],'C','F'); output=f

end

You forgot to mention what you want to provide as input and get as output. I guess you do not need varargin at all:

function output = c2f(Data)
output = convtemp(Data, 'C', 'F');
end

If you really want to provide several inputs, do you want to reply a cell array as output? Or a list of sepearate variables? For the latter:

function varargout = c2f(varargin)  % [EDITED, typo, was "nargin"]
if nargout ~= nargin
  error('Number of outputs must equal the number of inputs.');
end
for iArg = 1:nargin
  varargout{iArg} = convtemp(varargin{iArg}, 'C', 'F');
end
end

Thanks for your answer, but how can i do, if a have 8 input datas?

Yes exactly i want to reply a cell array as output.

To get a cell array as output:

function C = c2f(varargin)
C = cell(1, nargin);
for iArg = 1:nargin
  C{iArg} = convtemp(varargin{iArg}, 'C', 'F');
end
end

Now this can be called by:

Temperature = c2f(0:5, [123.1, 123.4, 123.9], Inf, -17:2:100)
