Optional graphics handle as first argument in function
显示 更早的评论
Hi,
similar to this question, I am creating some plotting functions and would like to stay consistent with Matlab built-in behavior. I.e. have a graphics handle (axes, figure, TiledChartLayout etc.) as an optional first argument for my functions (e.g. plot, nexttile).
I can see how to achieve it using varargin and an InputParser but am wondering if this can be done using the function argument validation scheme (which I appreciate a lot).

From my reading of the "Function Argument Validation" documentation here:
there is currently no way to have optional leading arguments like that.
Here is a possible untested workaround, by defining a very simple wrapper function:
function myfun(one,varargin)
if ishghandle(one)
locfun(one,varargin{:})
else
locfun(gcf,one,varargin{:})
end
end
function locfun(obj,A,B,C,...)
arguments
..
end
end
