Obviously providing a beta value of 1 0 would have made this example exactly the same as a regular add function with no transparency for the overlay text.
The name starts with a lower or upper case character hence a value between a z or a z.
Also note the extra parentheses required to avoid compilation errors.
Optional flag that conjugates the second input array before the multiplication true or not false.
