Nature of problem:
The spherical Bessel function appears in a variety of physical applications, and especially in phase shift analysis. The package SPHBES contains a subroutine to calculate jn(x) and yn(x) for any integer order n and real argument x. The functions jn(x) and yn(x) are produced simultaneously and efficiently.
The results are dependent on the size of the real number that can be accommodated by the computer. Due to partial cancellation of large numbers, precision is lost when both a large argument and a large order are involved.
The test run output took about 0.6 seconds.
