Hello,
I am currently encountering problems with function overloading within MATLAB R2017a.
I try to overload common functions such as abs and max among others. It seems to be simple but in fact for me it is not.
To do this, I create specific directories OVERLOAD\@single, OVERLOAD\@int32, OVERLOAD\@uint32 and OVERLOAD\@double. abs and max functions are redefined into @double and @single.
Overloaded abs function into @single is defined as: function [ output ] = abs(x) ...
overloaded max function is defined as: function [ output ] = max(varargin) ...
After adding path to OVERLOAD parent directory at ht beginning of path, I execute "which -all" command trying to understand which function is effectively called when executing abs and max. This is what I get:
>> which abs -all;
D:\Data\OVERLOAD\@single\abs.m % single method
D:\Data\OVERLOAD\@double\abs.m % double method
built-in (C:\Program Files\Matlab\R2017a\toolbox\matlab\elfun\@double\abs) % double method
...
>> which max -all;
built-in (C:\Program Files\Matlab\R2017a\toolbox\matlab\datafun\max)
D:\Data\OVERLOAD\@single\max.m % single method
D:\Data\OVERLOAD\@double\max.m % double method
...
It seems that overloading for max function appears in second position after built-in instead of first position.
Could anyone explain me why overloading is successful for abs and fails for max ?
Thanks for your attention.
