components.

Usage
i0(x) computes values of I-sub-0(x), the modified Bessel function of the
first kind, where x is a REAL scalar, vector, matrix or array. The
result is REAL of the same shape as x.
When x1, x2, ... are REAL, i0(structure(x1,x2,...)) returns
structure(i0(x1),i0(x2), ...)
i0 is based on equations 9.8.1 and 9.8.2 in Abramowitz & Stegun,
Handbook of Mathematical functions.
