both zero, they default to lo = 0 and hi = len / 2. The result is
returned in the complex array result, which must be preallocated, with
n rows and len columns, where n is hi - lo + 1. For the default values of
- lo and hi, n is len / 2 + 1. */
+ lo and hi, n is len / 2 + 1.
+ Clm: I don't think that lo and hi are actually specified in Hz but instead are in
+ units related to the length of the signal to be analyzed
