eljascf, eljasc, eljascl, eljascw, eljascq, eljascll, eljascdf, eljascd, eljascdl, eljascdll - inverse Jacobian elliptic function

SYNOPSIS

cc [ flags ] -I/usr/local/include file(s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>

extern float eljascf (float u, float k);

extern double eljasc (double u, double k);

extern long double eljascl (long double u, long double k);

extern __float80 eljascw (__float80 u, __float80 k);

extern __float128 eljascq (__float128 u, __float128 k);

extern long_long_double eljascll (long_long_double u, long_long_double k);

extern decimal_float eljascdf (decimal_float u, decimal_float k);

extern decimal_double eljascd (decimal_double u, decimal_double k);

extern decimal_long_double eljascdl (decimal_long_double u, decimal_long_double k);

extern decimal_long_long_double eljascdll (decimal_long_long_double u, decimal_long_long_double k);

NB: Functions with prototypes containing underscores in type names may be available only with certain extended compilers.


DESCRIPTION

Compute the inverse Jacobian elliptic function
eljasc(v, k) = asc(v, k) = u,
where
eljsc(u,k) = sc(u,k) = v.

The argument v is unrestricted, but the argument k (the modulus) is required to be in [-1,+1].

See M. Abramowitz & I. A. Stegun, Handbook of Mathematical Functions, Chapter 16, for definitions of the Jacobian elliptic, theta, and zeta functions.


RETURN VALUES

Return the inverse Jacobian elliptic function asc(v,k).

ERRORS

If either argument is a NaN, return that argument. If k is out of range, set errno to EDOM and return a quiet NaN.
