worksheet for w1simp.m demo
---------------------------


- make a new folder for week1.

  why this is so.  test other 
  values & data arrays:

  w1simp1([1 2 3])

  a complete list of variables
  computed within "w1simp" will
  result.  you can query the current
  value by simply typing the variable
  name.  (note:  this does not work 
  with function calls.)

  help xxxx

  where xxxx is any command.
  additional web-based help
