Algorithm Library for Diagnostics Tools

 

Laser Interferometer Gravitational-Wave Observatory

Algorithm Library 3/13/00
The diagnostics algorithm library supports:
  • Time conversion between UTC and GPS seconds.
  • Common numerical and physical constants.
  • Random number generator.
  • Decimation and upsampling algorithms.
  • Averaging algorithms.
  • Fourier analysis (FFT, power spectrum, coherence, cross-spectrum, windowing).
  • Sine analyze algorithms
  • LU Decomposition

    • A preprocess functions is also supported which collects, upsamples, time delays, decimates, down-converts, decimates, time shifts and partitions the data.

    Installation
    Get the source code distribution and follow the README file.
    The code was tested under Solaris 2.6 and Solaris 2.7 using the SUN sparcworks 5.0 compilers.
    This library requires FFTW.
