- *	Modified Bessel function, third kind, order one
- *
- *
- *
- * SYNOPSIS:
- *
- * double x, y, k1();
- *
- * y = k1( x );
- *
- *
- *
- * DESCRIPTION:
- *
- * Computes the modified Bessel function of the third kind
- * of order one of the argument.
- *
- * The range is partitioned into the two intervals [0,2] and
- * (2, infinity).  Chebyshev polynomial expansions are employed
- * in each interval.
- *
- *
- *
- * ACCURACY:

- * arithmetic   domain     # trials      peak         rms
