Keep the name, but change the engine by using the more robust ERFC function:

p = 0.5 * erfc(-z ./ sqrt(2))

Do not print the results out on the screen as well, but just return them as an output argument.

Finally, re-design the help section (add H1 line, used by lookfor), a description of the inputs and outputs, an example and a see also line.
