BUILTIN BUILTIN Evaulate Builtin Function

Usage

The builtin function evaluates a built in function
with the given name, bypassing any overloaded functions.
The syntax of builtin is

  [y1,y2,...,yn] = builtin(fname,x1,x2,...,xm)

where fname is the name of the function to call.  Apart
from the fact that fname must be a string, and that builtin
always calls the non-overloaded method, it operates exactly like
feval.  Note that unlike MATLAB, builtin does not force
evaluation to an actual compiled function.  It simply subverts
the activation of overloaded method calls.
