One of the things that is easy in IDL that I occasionally wish I knew
how to do easily in octave is to write fully functional wrapper
functions. I've never succeeded in doing this simply in octave/matlab
but probably it's a limitation of my octave/matlab skills.
As a simple exercise, how does one create a wrapper to plot() that
simply adds "markersize",3 to the property list and then calls plot?
This doesn't work:
function myplot(varargs)
return plot(varargs, "markersize",3)
endfunction
plot(1:4,"*","markersize",3)
myplot(1:4,"*")
myplot(1:4,"*","color","red")
I've tried other things but I haven't figured it out. Bonus points if
you figure out how to get it to work with varargout functions.
