builtin
Calls the built-in version of a function, ignoring any overriding file.
Category: Programming > Classes
Syntax
[y1, ..., yN] = builtin(name, x1, ..., xM)Calls the built-in function name with the given arguments.
Description
When you write your own function with the same name as a built-in, yours takes precedence in calls. Inside it, builtin is the way to reach the original, for example to wrap size with extra checks and then delegate to the standard one.
The number of outputs requested from builtin is passed on to the function.
Input arguments
name- Name of a built-in function, as text.
x1, ..., xM- Arguments passed to that function.
Output arguments
y1, ..., yN- Outputs of the built-in function.
Example
Calling built-ins by name
builtin('sum', [1 2 3])
[m, i] = builtin('max', [4 9 2]);
fprintf('max %d at %d\n', m, i)
builtin('upper', 'abc')Output
ans = 6
max 9 at 2
ans = 'ABC'
