besseli - Modified I sub ALPHA Bessel functions of the first kind.
8
y = besseli(alpha,x,ice)
13
: real vector with non negative entries
16
: real vector with non negative entries regularly spaced with
17
increment equal to one \fValpha=alpha0+(n1:n2)\fR
20
: integer flag, with default value 1
23
\fVbesseli(alpha,x)\fR computes I sub ALPHA modified Bessel functions of the
24
first kind, for real, non-negative order \fValpha\fR
25
and argument \fVx\fR. \fValpha\fR and \fVx\fR may be vectors.
26
The output is \fVm\fR-by-\fVn\fR with \fVm = size(x,'*')\fR,
27
\fVn = size(alpha,'*')\fR whose \fV(i,j)\fR entry is
28
\fVbesseli(alpha(j),x(i))\fR.
