besselk - Modified K sub ALPHA Bessel functions of the second kind.

Calling Sequence

y = besselk(alpha,x)

y = besselk(alpha,x,ice)

Parameters

• x : real vector with non negative entries
• alpha : real vector with non negative entries regularly spaced with increment equal to one alpha=alpha0+(n1:n2)
• ice : integer flag, with default value 1

Description

besselk(alpha,x) computes K sub ALPHA modified Bessel functions of the second kind, for real, non-negative order alpha and argument x. alpha and x may be vectors. The output is m-by-n with m = size(x,'*'), n = size(alpha,'*') whose (i,j) entry is besselk(alpha(j),x(i)).

If ice is equal to 2 exponentialy scaled Bessel functions is computed

Examples

besselk(0.5:3,1:4)
besselk(0.5:3,1:4,2)
