Working on my 'Bessel' package, I've re-detected today, that indeed even C99 standard GLIBC does not contain, a complex number version of
log1p() Further missing in current R, are, basically these > z <- 1 + 2i > log1p(z) Error in log1p(z) : unimplemented complex function > expm1(z) Error in expm1(z) : unimplemented complex function > gamma(z) Error in gamma(z) : unimplemented complex function > lgamma(z) Error in lgamma(z) : unimplemented complex function > psigamma(z) Error in psigamma(z) : unimplemented complex function > digamma(z) Error in digamma(z) : unimplemented complex function > sinpi(z) Error in sinpi(z) : unimplemented complex function > cospi(z) Error in cospi(z) : unimplemented complex function > floor(z) Error in floor(z) : unimplemented complex function > ceiling(z) Error in ceiling(z) : unimplemented complex function > -------------- Is anyone aware of Free Software implementations of these, ideally in C ? ... yes, I think I've found the Julia source code for these, nicely written in Julia itself...
