Hints:
  1. e is coded as exp(1) if you are talking about the base of the natural logarithms.
  2. you need a multiplication symbol before your final '('
  3. you need to have the same number of ')' as you have '('
  4. commas are not permitted as thousand groupings in numbers
  5. http://www.mathworks.com/help/techdoc/ref/for.html
  6. are you really using e as a single constant, or does your original formula have e raised to some power? If it does have e raised to a power, see http://www.mathworks.com/help/techdoc/ref/exp.html
