|1||GETASCII.f||This program shows the binary structures of the ASCII code.|
|1||ascii_test.f||Example of Fortran Program to determine the ASCII code of a given character and vice versa.|
Example of Fortran Program to determine the binary structure of a given integer number.
|1||real_test.f||Example of Fortran Program to determine the binary structure of a given real number.|
|1||maximum_test.f|| Example of Fortran Program to determine the extrema of the real number & integer number that can be resolved by the current computing system.
(Note that the extrema are not unique but are machine dependent.)
|1||GETU.f||This single-precision subroutine determines machine-dependent relative error relative to 1.|
|1||DGETU.f||This double-precision subroutine determines machine-dependent relative error relative to 1.|
|2||Fast Fourier Transform||This is the Fast Fourier transform code originally published at IBM/SSP. This code has been modified by Prof. John Dawson's group in UCLA to fit in the prticle simulation codes developed at UCLA. Ling-Hsiao Lyu made additional modification in response to the default setting in most of the modern FORTRAN compliers.|
|4||ran.f||This function obtains a machine-dependent uniform random number.
This function is good for 32 bits computer.
This function is modified from IBM/SSP subroutine RANDU
|4||ran_func.f||This subroutine obtains a random number of a given function FUNC(x).|
|4||GAUSS.f||This subroutine obtains a random number of a normal distribution function with a given mean and standard deviation based on the method described on page 77 in IBM/SSP.|
|6||1-D electrostatic particle code||This code originally come from UCLA. This is a second-order finite-size particle code. Spatial deposiition is constructed based on the dipole approximation. Time integration is constructed based on the leap-frog method.
It has been modified by Ling-Hsiao Lyu in response to the default setting in the modern FORTRAN compliers. The input parameters are good for study electron-electron, or electron-ion, or ion-ion two-stream instabilities.
