NAMEj0(), j0f(), j0l, j0w(), j0q(), j1(), j1f(), j1l(), j1w(), j1q(), jn(), jnf(), jnl(), jnw(), jnq() — Bessel functions of the first kind SYNOPSIS#include <math.h> double j0(double x); double j1(double x); double jn(int n, double x); HP Integrity Server Onlyfloat j0f(float x); float j1f(float x); float jnf(int n, float x); long double j0l(long double x); long double j1l(long double x); long double jnl(int n, long double x); extended j0w(extended x); extended j1w(extended x); extended jnw(int n, extended x); quad j0q(quad x); quad j1q(quad x); quad jnq(int n, quad x); DESCRIPTIONj0() and j1() return Bessel functions of x of the first kind of orders 0 and 1 respectively. jn() returns the Bessel function of x of the first kind of order n. j0f(), j1f(), and jnf() are float versions of j0(), j1(), and jn(); each takes a float argument x and returns a float result. j0l(), j1l(), and jnl() are long double versions of j0(), j1(), and jn(); each takes a long double argument x and returns a long double result. j0w(), j1w(), and jnw() are extended versions of j0(), j1(), and jn(); each takes an extended argument x and returns an extended result. j0q(), j1q(), and jnq() are quad versions of j0(), j1(), and jn(); each takes a quad arguemnt x and returns a quad result. USAGETo use these functions, compile either with the default -Ae option or with the -Aa and -D_HPUX_SOURCE options. Make sure your program includes <math.h>. Link in the math library by specifying -lm on the compiler or linker command line. To use (for Integrity servers) j0w(), j1w(), jnw(), j0q(), j1q(), or jnq(), compile also with the -fpwidetypes option. |
