[SEM20-P14] Multi-platform applications generated from MATLAB codes for viewing and analyzing demagnetization and directional data
Keywords:paleomagnetism, software, demagnetization, MATLAB
There are two separate applications available: for viewing and fitting stepwise demagnetization data on Zijderveld and equal-area plots, and for viewing directional data on an equal-area plot and calculating the Fisher statistics. The data format remains simple; for demagnetization data it just needs three parameters in a polar coordinate of declination, inclination and intensity at each demagnetization level. For directional data only declination and inclination are necessary for each specimen or site. Users can confirm demagnetization intervals to be fitted on Zijderveld and equal-area plots before performing the fitting. Fitted data can be exported to a text file and handed out to the direction application. Fisher statistics parameters can be stored in a text file. You can save drawings in a variety of format such as pdf, jpeg, tiff, bmp etc. Later you can process the drawings for presentation or manuscript preparation with graphic softwares.
Both applications run on Windows (32 and 64 bits), Macintosh OS X, and Linux. Any MATLAB license is not needed to use the applications, just download a software package at http://mpms.doshisha.ac.jp/pd16/pd16top.html and MATLAB Runtime will be automatically installed. The MATLAB source code is also available, so if you prefer you can run the MATLAB programs and also modify them on your own right. Future update of the applications adapted to updated OS will be easily carried out by ourselves or others using updated MATLAB.
