Calling a function with no arguments

Hi All,
In my program , I'm trying to call a function with some input arguments but no outputs as I'm using this function for the purpose of plotting.
How should its syntax look like?
[ ] = function_name( var1,var2,var3) // This line is giving me erorr : Assigning an output to an empty array is not supported.
Please suggest me a way to handle this error.
Thanks in advance!

If you're using a function to plot, you can return the handles to the graphics object, just like the plot function does.

You can achieve it this way.
function function_name( var1,var2,var3)
However, imagine a situation where you'd like to edit something on the plot that you've made, then you'd have to find the handles of it which is not a problem if you have only one figure/axes, but for multiples, you could return a figure handle.
function hFigure = function_name( var1,var2,var3)
hFigure = figure(1); % if you're using it
plot(hFigure, x, y);
end

@Mario Malic: are you sure about that function definition syntax? The syntax given in the documentation is:
function hFigure = function_name(var1,var2,var3)

I haven't had my first coffee yet! I edited the answer, thanks Stephen.
