MExtremes

A MATLAB®-based Generator of Extreme-Event Tables

by Greg Hayman
National Wind Technology Center

MExtremes (pronounced em-extremes) is a set of MatLab scripts that generate extreme-event tables for one or more time series.  Although we developed MExtremes to process wind turbine test or simulation data, it may also be useful for other types of data.

MExtremes generates the same tables as Crunch and MCrunch, but only one time series needs to reside in memory at once, so it uses far less memory.  It should be much faster than MCrunch when processing many files.  Unlike Crunch and MCrunch, you can process an entire loads suite in a single job.

    This is the self-extracting archive of the latest alpha version of MExtremes.  Simply execute it in an appropriate directory to extract the files. It contains a ReadMe file, alpha change log, the source code, sample data files, a certification script to test your installation, and a compiled version of the code.  The scripts are compatible with MatLab 7.13.0 (R2011b)®.

  • MatLab Component Runtime Installer (win32) (v7.16, 396.8 MB, 14-August-2011)
  • MatLab Component Runtime Installer (win64) (v7.16, 413.4 MB, 14-August-2011)

    If you do not own MatLab and want to be able to use MExtremes, you will have to use the compiled version of MExtremes. The MatLab Component Runtime (MCR) is a library of support routines you need to run the compiled version of MExtremes. The MCR is free.  You must install it as a Windows application before using the compiled version of MExtremes. We support only Windows with the compiled version. The other files you need to run the compiled version are located in MExtremes's Compiled folder.
