Runtime multiple dispatch for Matlab.

>> foo(true,2)
Index exceeds the number of array elements (1).
Error in dispatch>isa_ (line 73)
varisa(i) = isa2(var{i},type{i});
Error in dispatch>ismethod (line 42)
out = isa_(var, numOrType);
Error in dispatch (line 24)
if ismethod(var, methodTable{i,2})
Error in foo (line 3)
out = dispatch(varargin,...
Though it works if I remove the dispatch to the "Person" class in the methodTable
. I believe this happens because of the effective weak-typed use of numOrType
in ismethod
.
On a side note I think you probably could enable multiple outputs by just making use of varargout
and collecting from the specialized implementation everything as [varargout{1:nargout}]
. This was the initial patch I was targeting, but the fundamental design issue (in my view) with collision between dispatch on number of (numeric-only) and on non-numeric types has made me desist. Nevertheless I find the idea of building an "julia-like" ergonomic interface for multiple dispatch via isa
quite interesting, I might return on this when I have time: matlab has all the needed functionality for that, just a painful API. Thanks for the idea :)
