I previously wrote about typing elliptic fourier series; my Apple compiler is now capable of computing the offsets and also the relevant coefficients.
To compute a 7-day moving average:
As I wrote about previously I am working on a typed array language with the case of elliptic Fourier series as an example.
Elliptic Fourier series are a good example to kick the tires on array programming systems; J and Python, however, are both dynamically typed.
J and APL support (and encourage) a certain form of programming without error handling or library code reuse. The alternative wisdom goes against typical programming but it works together.
