MATLAB: Naming Variables wit using varargin.

functionvariable

Hello everyone. I define a Gama function which must had 4 inputs. If we entered more than 4 inputs it should say Error!. I must use the variables that taken from inside of the varargin to an equation like this fun= (sin(2*pi.*f.*(m-n).*T))/ 2*pi.*f.*(m-n).*T; but how can i name my variables? For example if i entered Gama(1,3,5,7) the first value should represents m ,the second value should represents n and the others represents f and t. How can i name them and use it into my function. Thanks for your help. Have a Good Day.
    function Gama(varargin)
if nargin<=4
    disp("Number of input arguments: " + nargin)
    disp(varargin)
else
    'Error'
    f=varargin{1}
    m=varargin{2}
    n=varargin{3}
    T=varargin{4}
    if nargin<=4
    fun= (sin(2*pi.*f.*(m-n).*T))/ 2*pi.*f.*(m-n).*T;
    t=1:1:100;
    figure
    plot(fun,t)
    xlabel('Omega')
    ylabel('Gamma')
    else
        'Error! More Than 4 Inputs entered'
    end

Minor modifications are needed
    function Gama(varargin)
    if nargin < 4
      error('Not enough inputs entered')
    elseif nargin > 4
      error('Too many inputs entered')
    end
    f=varargin{1}
    m=varargin{2}
    n=varargin{3}
    T=varargin{4}
    T=1:1:100;
    fun= (sin(2*pi.*f.*(m-n).*T))/ 2*pi.*f.*(m-n).*T;
    figure
    plot(T, fun)
    xlabel('Omega')
    ylabel('Gamma')
I would, however, recommend that you consider the possibility that you instead want
    fun= (sin(2*pi.*f.*(m-n).*T)) ./ (2*pi.*f.*(m-n).*T);
