Wave Analysis for Fatigue and Oceanography (WAFO) is a toolbox of Matlab routines for statistical analysis and simulation of random waves and random loads.

Fatigue Analysis

• Fatigue life prediction for random loads
• Theoretical density of rainflow cycles

Sea modelling

• Simulation of linear and non-linear Gaussian waves
• Estimation of seamodels (spectrums)
• Joint wave height, wave steepness, wave period distributions

Statistics

• Extreme value analysis
• Kernel density estimation
• Hidden markov models
• Multivariate Gaussian probabilities and expectations
• Profile log-likelihood analysis
• Regression analysis
• Hypothesis tests (one-sample and two sample T-test, Wilcoxon signed rank and rank-sum test,....)
• Probability distributions and random number generators (Beta, Chi-2, Exponential, Gamma, GPD, GEV, Gumbel, Inverse Gaussian, Lognormal, Normal, Rayleigh, Students-T, Weibull,...)

• Bootstrap
• Design of Experiments

Numerics

• Derivatives (gradient, hessian, jacobian)
• Integration (Gaussian quadratures (1D and 2D), simpson, Clenshaw-Curtis)
• Smoothing spline
