MATLAB: Help needed with variables within functions!!

dimensionsvariables

hello there if there is a function that depends on 3 variables t,x and y [f(t,x,y)] but inside this function is another function that is independent on y [g(t,x,?)], how do I tell matlab to ignore the y term?

• Just do not pass y to g?
Or edit g to add varargin as the last function argument, something like
function result = g(t,x,varargin)
and then just have g ignore varargin ?
Or if you have a newer (2009a or later?) MATLAB, edit g to add ~ as the last function argument, something like
function result = g(t,x,~)
Or if you have an older MATLAB, edit g to add y as the last argument but do not use y in g, something like
function result = g(t,x,y)
