BESSEL_JN
— Bessel function of the first kindBESSEL_JN(N, X)
computes the Bessel function of the first kind of
order N of X. This function is available under the name
BESJN
as a GNU extension. If N and X are arrays,
their ranks and shapes shall conform.
BESSEL_JN(N1, N2, X)
returns an array with the Bessel functions
of the first kind of the orders N1 to N2.
BESSEL_JN(N1, N2, X)
RESULT = BESSEL_JN(N, X)
|
RESULT = BESSEL_JN(N1, N2, X)
|
N | Shall be a scalar or an array of type INTEGER .
|
N1 | Shall be a non-negative scalar of type INTEGER .
|
N2 | Shall be a non-negative scalar of type INTEGER .
|
X | Shall be a scalar or an array of type REAL ;
for BESSEL_JN(N1, N2, X) it shall be scalar.
|
REAL
. It has the same
kind as X.
