## The following functions are available for computing the values of
## Bessel functions:
##
## besselj (alpha, x) Bessel functions of the first kind
## bessely (alpha, x) Bessel functions of the second kind
## besseli (alpha, x) modified Bessel functions of the first kind
## besselk (alpha, x) modified Bessel functions of the second kind
##
## X must be a real matrix, vector or scalar.
##
## If ALPHA is a scalar, the result is the same size as X. If ALPHA is
## a range, X must be a vector or scalar, and the result is a matrix
## with length(X) rows and length(ALPHA) columns.
##
## ALPHA must be greater than or equal to zero. If ALPHA is a range, it
## must have an increment equal to one.
