"Make uncertainty quantification available for anybody,

in any field of applied science and engineering"

  • MATLAB®-based Uncertainty Quantification framework

  • State-of-the art, highly optimized open source algorithms

  • Fast learning curve for beginners

  • Modular structure, easy to extend

  • Exhaustive documentation

  • 9 September 2020: Abdulrauf Khetrish, a master's student in Civil and Environmental Engineering at the University of Sharjah (United Arab Emirates) is the 3,000th registered user of UQLab since the first public release in July 2015.
    Abdulrauf will use UQLab during his course on Applied Engineering Statistics to do uncertainty and reliability analysis, and plans to further use it in his master thesis.
    Virtually on the same day, we got the 500th registration from the USA, and the 300th one from France. China, with 370 registered users completes this top trio of countries.

  • 19 September 2019: UQLab Modules Rel 1.3 is released. The release includes a new reliability-based design optimization (RBDO) module, a statistical inference module, and an overhauled Input module, now with much more advanced dependence modelling. Check out the Release notes  for more details.

UQLab is a general purpose Uncertainty Quantification framework developed at ETH Zurich (Switzerland). It is made of open-source scientific modules which are smoothly connected through UQLab to carry out uncertainty propagation through Monte Carlo sampling, sensitivity analysis, reliability analysis (computation of rare event probabilities), build surrogate models (polynomial chaos expansions, Kriging, low-rank tensor approximations, etc.) and more.

UQLab, the content management system that allows for an easy use of UQLab modules, can be downloaded here .

It is completely free for academic users: academic registration form

For non-academic users: commercial registration form .

UQLab is developed at the Chair of Risk, Safety and Uncertainty Quantification of ETH Zurich under the supervision of Prof. B. Sudret and Dr. S. Marelli.
