ExampleSeven gives warnings about deprecated NumPY API #3

Closed cbm755 closed 5 years ago

I ran python3 ExampleSeven.py:

(It then dies with a Segmentation fault (core dumped), which I assume is Issue #2.)

This warning is a known problem with the f2py module.

See: https://github.com/cython/cython/issues/2498

I will look into the segfault (and issue #2).
