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)
