Dilog function

Dilog functions

Dilog functions as per the Gnu Scientific Library reference manual section 7.11. These functions are declared in header file gsl_sf_dilog.h

dilog(x, give=FALSE, strict=TRUE)
complex_dilog(r, theta, give=FALSE, strict=TRUE)

Arguments

• x: input: real values

• r,theta: In complex_dilog(), input values. If theta takes its default value of NULL, interpret r as a complex-valued object. If theta is non-null, interpret r as the Modulus, and theta as the argument, of the complex object passed to gsl_sf_complex_dilog_e()

• give: Boolean, with default FALSE meaning to return just the answers, and TRUE meaning to return a status vector as well

• strict: Boolean, with TRUE meaning to return NaN

  if nonzero status is returned by the GSL function (FALSE

  means to return the value: use with caution)

Details

All functions as documented in the GSL reference manual section 7.11.
