BESELJ
The
BESELJ function returns the J 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. BESELJ uses the
j0(3M)
,
j1(3M)
, and
jn(3M)
functions from the standard C math library.
Calling Sequence
Result = BESELJ(
X
,
N
)
Arguments
X
The expression for which the J Bessel function is required. The result has the same dimensions as
X
.
N
The order of the J Bessel function to calculate.
N
must be an integer greater than or equal to 0.
