The
BESELI function returns the I 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.

Calling Sequence

Result = BESELI(
X, N
)

Arguments

X

The expression for which the I Bessel function is required. The result will have the same dimensions as
X
.

N

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