BESELY

The
BESELY function returns the Y Bessel function of order *
N*
for the argument *
X*
. If *
X*
is double-precision, the result is double precision, otherwise the argument is converted to floating-point and the result is floating-point. BESELY uses the ```
y0(3M)
```

, ```
y1(3M)
```

, and ```
yn(3M)
```

functions from the standard C math library.

###
Calling Sequence

Result = BESELY(*
X, N*
)

###
Arguments

####
X

The expression for which the Y Bessel function is required. *
X*
must be greater than 0. The result has the same dimensions as *
X*
.

####
N

The order of the Y Bessel function to calculate. *
N*
must be an integer greater than or equal to 0.
