25 ## besseli (alpha, x) modified Bessel functions of the first kind 25 ## Compute Bessel functions of the following types:

28 ## X must be a real matrix, vector or scalar. 28 ## @item besselj
29 ## 29 ## Bessel functions of the first kind.
30 ## If ALPHA is a scalar, the result is the same size as X. If ALPHA is 30 ##
31 ## a range, X must be a vector or scalar, and the result is a matrix 31 ## @item bessely
32 ## with length(X) rows and length(ALPHA) columns. 32 ## Bessel functions of the second kind.
33 ## 33 ##
34 ## ALPHA must be greater than or equal to zero. If ALPHA is a range, it 34 ## @item besseli

37 ## @item besselk
38 ## Modified Bessel functions of the second kind.
