t = 1790:2000;
p = 197273000./(1+exp(1)-.0313*(t-1913.25));

That does not do what zizo asked: it will not create p(1790) to p(2000)

Hints:
- e is coded as exp(1) if you are talking about the base of the natural logarithms.
- you need a multiplication symbol before your final '('
- you need to have the same number of ')' as you have '('
- commas are not permitted as thousand groupings in numbers
- http://www.mathworks.com/help/techdoc/ref/for.html
- 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
