BESSEL_YN — Bessel function of the second kind
BESSEL_YN(N, X)computes the Bessel function of the second kind of order N of X. This function is available under the name
BESYNas a GNU extension. If N and X are arrays, their ranks and shapes shall conform.
BESSEL_YN(N1, N2, X)returns an array with the Bessel functions of the first kind of the orders N1 to N2.
Fortran 2008 and later, negative N is allowed as GNU extension
Elemental function, except for the transformational function
BESSEL_YN(N1, N2, X)
RESULT = BESSEL_YN(N, X)
RESULT = BESSEL_YN(N1, N2, X)
N Shall be a scalar or an array of type
N1 Shall be a non-negative scalar of type
N2 Shall be a non-negative scalar of type
X Shall be a scalar or an array of type
BESSEL_YN(N1, N2, X)it shall be scalar.
- Return value:
The return value is a scalar of type
REAL. It has the same kind as X.
The transformational function uses a recurrence algorithm which might, for some values of X, lead to different results than calls to the elemental function.
