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
