Arguments
zr
In gamma_complex()
, the real part of the argument
zi
In complex_sin()
et seq, the imaginary part of the
argument. If missing (ie takes the default value of NULL
),
interpret zr
as complex, even if rea.
r.and.i
In complex_sin()
et seq, Boolean variable with
default value of TRUE
meaning to return a complex variable as
per the details section below; and FALSE
meaning to return
the values as advertised in the GSL
give
Boolean with TRUE
meaning to return a list of three
items: the value, an estimate of the error, and a status number.
strict
Boolean, with TRUE
meaning to return NaN
if status is an error
