The log function operates element-wise on
arrays. Its domain includes complex and negative numbers, which may
lead to unexpected results if used unintentionally.
Y = log(X) returns the
natural logarithm of the elements of X. For complex
or negative z where z = x + y*i,
the complex logarithm is returned.
log(z) = log(abs(z)) + i*atan2(y,x)
The statement abs(log(-1)) is
a clever way to generate π.
