Structure variable as input in MATLAB function using VARARGIN

I wrote a main function in Matlab that calls other functions, each of which produces plots in a new figure. Though each function produces different plots (different colors, number of subplots, and so on) they all share some features (font, fontsize, Linewidth etc.). In order to make it easier to modify the aforementioned shared parameter for all the MATLAB figures, I have defined in the preamble of the main function a structure variable as follows:
var.font = 'Arial Unicode MS';
var.fontsize = 13;
var.interpreter = 'none' ;
and so on for the other fields. When I call the function in this way (providing the structure as input):
function plot1( var , ... )
fig = gcf
fig.Position(3) = var.Position3
fig.Position(4) = var.Position4
end
everything works fine and the functions apply the feature to each figure. But if I try to provide a variable number of input to the functions using varargin, in this way
function plot1( varargin )
fig = gcf;
temp = varargin(1);
fig.Position(3) = temp.Position3;
fig.Position(4) = temp.Position4;
end
The following error message is prompted "Struct contents reference from a non-struct array object."

function plot1( varargin )
var = varargin{1} ;
fig = gcf;
temp = var(1);
fig.Position(3) = temp.Position3;
fig.Position(4) = temp.Position4;
end
