FUNCTIONS

13   gsl_sf_log
14         Signature: (double x(); double [o]y(); double [o]e())
15
16       Provide a logarithm function with GSL semantics.
17
18       gsl_sf_log does not process bad values.  It will set the bad-value flag
19       of all output ndarrays if the flag is set for any of the input
20       ndarrays.
21
22   gsl_sf_complex_log
23         Signature: (double zr(); double zi(); double [o]x(); double [o]y(); double [o]xe(); double [o]ye())
24
25       Complex Logarithm exp(lnr + I theta) = zr + I zi Returns argument in
26       [-pi,pi].
27
28       gsl_sf_complex_log does not process bad values.  It will set the bad-
