Usage
gsl_sf_log(x, give=FALSE, strict=TRUE)
log_abs(x, give=FALSE, strict=TRUE)
complex_log(zr, zi=NULL, r.and.i=TRUE, give=FALSE, strict=TRUE)
log_1plusx(x, give=FALSE, strict=TRUE)
log_1plusx_mx(x, give=FALSE, strict=TRUE)
Arguments
zr
In complex_log(), the real part of the argument
zi
In complex_log(), the imaginary part of the
argument. If missing (ie takes the default value of NULL),
interpret zr as complex, even if real.
r.and.i
In complex_log(), Boolean variable with
default value of TRUE meaning to return a complex variable as
per the details section below; and FALSE meaning to return
