How to imitate Matlab's plot function in plot function made by user?

I have created a plot function with three arguments as

 fun(xvar, norm1, var1)
plot(xvar, fun(norm1,var1))
end

My problem is that I can't assign some attributes to the plot function, as It is possible in Matlab's default plot function. To be specific, I want to change plot's properties like line style, color and etc in my function. How should I change the function to do this? Like:

 fun(xvar, norm1, var1, 'color', 'r', 'linestyle', '--')

Any help is appreciated.

Use varargin:

function my_fun(xvar, norm1, var1, varargin)
plot(xvar, other_fun(norm1,var1), varargin{:});
end

This simply passes any extra optional arguments directly to plot.
