middle square algorithm in MATLAB

How to do the following question:

Use the middle square algorithm which takes a seed (max 8-digits), squares the middle 4 to return a new random number (normalized so the range is 0-1). The returned value is used as the seed for the next draw, if the number has less than 8 digits, pad the beginning of the number with zeros before selecting the middle four digits. for example, set seed 00159839 in the begining

mengke - what have you tried so far? Why do you need to normalize the number to the range 0-1? Isn't this the psuedo random number whose middle four digits you extract (padding if necessary) to generate a new pseudo random number? How would you do that if the number is normalized?
