J = besselj(alpha,x)
J = besselj(alpha,x)
computes Bessel functions of the first kind for real, non-negative order alpha
and argument x
. If alpha
is a scalar and x
is a vector, J
is a vector the same length as x
. If x
is a vector of length m
and alpha
is a vector of length n
, then J
is an m
-by-n
matrix and J(i,k)
is besselj(alpha(k), x(i))
. The elements of x
can be any nonnegative real values, in any order. For alpha
, the increment between elements must be 1, and all elements must be between 0 and 1000, inclusive.
besselj
uses three-term recurrence for most x
, and an asymptotic series for large x
.
