argument. | ||

Programming language: Fortran. | ||

Computer: CDC 6600. | ||

Operating system: CDC SCOPE. | ||

RAM: 3K words | ||

Word size: 60 | ||

Keywords: Acoustic, Spherical Bessel function, Radial, Partial wave, Phase shift, General purpose. | ||

Classification: 4.7. | ||

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. | ||

Restrictions: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. | ||

Running time:The test run output took about 0.6 seconds. |
