WAFO Toolbox
Version 2.1.1 07-Sep-2005
Wave Analysis for Fatigue and Oceanography (WAFO) Toolbox
The WAFO toolbox is mainly developed at
Mathematical statistics, Lund University, Sweden
<http://www.maths.lth.se/matstat/>
see 'wafocredits' for further information.
WAFO consists of several modules (directories) with short descriptions below.
The modules SPEC, TRGAUSS, WAVEMODELS, and MULTIDIM are mainly for
oceanographic applications.
The modules CYCLES, MARKOV, and DAMAGE are mainly for fatigue problems.
The contents file for each module is shown by typing 'help module-name'
Type 'help fatigue' for a presentation of all routines related to fatigue.
The paths to the modules are initiated by the function 'initwafo'.
ONEDIM - Data analysis of time series. Example: extraction of
turning points, estimation of spectrum, covariance function.
SPEC - Computation of spectral moments and covariance functions.
Ex: common spectra implemented, directional spectra,
bandwidth measures
TRGAUSS - Modelling with linear, Gaussian waves. Ex: exact
distributions for wave characteristics, transformed
Gaussian processes
WAVEMODELS - Models for distributions of wave characteristics found in
the literature. Ex: parametric models for breaking
limited wave heights.
MULTIDIM - Multi-dimensional time series analysis. (Under construction)
CYCLES - Cycle counting, discretization, and crossings. Ex: Rainflow
cycles and matrix, discretization of loads.
MARKOV - Routines for Markov loads, switching Markov loads, and
their connection to rainflow cycles.
DAMAGE - Calculation of damage. Ex: Damage of a rainflow count or
matrix, damage matrix, S-N plot.
WSIM - Simulation of random processes. Ex: spectral simulation,
simulation of discrete Markov chains, switching Markov
chains, harmonic oscillator
WSTATS - Statistical tools and extreme-value distributions.
Ex: generation of random numbers, estimation of parameters,
evaluation of pdf and cdf
KDETOOLS - Kernel-density estimation.
MISC - Miscellaneous routines. Ex: numerical integration, smoothing
spline, binomial coefficient, water density.
WDEMOS - WAFO demos.
DOCS - Documentation of toolbox, definitions. An overview is given
in the routine wafomenu.
DATA - Measurements from marine applications.
PAPERS - Commands that generate figures in selected scientific
publications.
SOURCE - Fortran and C files. Information on compilation.
EXEC - Executable files (cf. SOURCE), pre-compiled for Solaris,
Alpha-Dec or Windows.
