# Element wise sum and multiplication
np.array([3, 1]) + np.array([2, 1]) # => np.array([5, 1])
np.array([3, 1]) * np.array([2, 1]) # => np.array([6, 1])

# Square root
np.sqrt(np.array([1,2])) # => array([1, 1.41421356])

# Magnitude of a vector
np.linalg.norm(np.array([1, 2])) # => 2.23606797749979

# accidentally committing, like temporary IP addresses or debug printfs.
#
# To add it to an existing repository, save it to .git/hooks/pre-commit (or append, if
# that file already exists). Remember to make executable (chmod +x ...)
