Having unimputed data default to a value

Hello, I am writing a function that takes an input and size parameters and exports it as a dot file.

function(input, width, height)

incToDot(KGraph,width,height,1.0,NameofDotFile); (width height are size parameters for the dot file)

I like having the option to change the size parameters in the function but i would also like my function to default so that width and height are not needed. ie if i was simply to type in

function(input)

(it would default to)

incToDot(KGraph,8.0,8.0,1.0,NameofDotFile);

Please do not call a variable "input": you will very likely run in to conflicts with the built-in MATLAB function by that name.

function PlotIt(KGraph, width, height)
  if ~exist('width', 'var')
    width = 8.0;
  end
  if ~exist('height', 'var')
    height = 8.0;
  end
  incToDot(KGraph,width,height,1.0,NameofDotFile);
end
