Generate correct ezplot for 2-input functions (bug #46004). * __ezplot__.m: Convert string name of m-files or built-in functions to a function handle rather than an inline function. Eliminate 1/3rd of input processing that was for string inputs. Use nargin to find whether input function uses 2 inputs.
