builtin

不太懂overload是什麼  所以很多不知道怎麼翻譯 Execute builtin function from overloaded method

Syntax

Description

builtin is used in methods that overload builtin functions to execute the original builtin function. 若 function 中包括內建函式(builtin function)的名字,則:

builtin(function,x1,...,xn) 根據給定的引數和函式來執行。

[y1,..,yn] = builtin(function,x1,...,xn) 回傳多個輸出引數。

Remarks

builtin(...) is the same as feval(...) except that it calls the original builtin version of the function even if an overloaded one exists. (For this to work you must never overload builtin.)
