initialize normal random number generator

sets the state for Matlab's normal (Gaussian) random number generator

Description

initrandn() sets the state for Matlab's normal (Gaussian) random number generator. (Matlab has two generators-- 'rand' and 'randn'-- for uniform and normal random numbers, respectively. Each of these maintains its own state).

If the optional calling argument is missing, initrandn() prompts the user to enter a seed interactively. If the optional calling argument is present but is an empty matrix, or if the user input is empty, a default seed is generated based on the current date and time.
