MATLAB: Optionally create plots inside function

functionplot

I have a function

y=myfun(x)
y=3*x;
plot(x, y)

If x=[1 2 3 4 5]; then the plot will be plotted. Is there anyway to control if I want to make the plot or not?

Yes. Don't call plot() if you don't want it plotted.

You would use varargin,

function theFunction(varargin)
  for i=1:numel(varargin)
      
      matrix=varargin{i};
      
      ...
  end
end

It should be

x = linspace(1,10,100);
y = (2./x).^3;
plot(x,y,'linewidth',4,'color','r')
