Reading and Processing XrdML Files Storing X-Ray Powder Diffraction (XRD) Data With MATLAB

The XrdML file format is used to store X-ray powder diffraction measurements. Since XrdML format using the .xrdml file extension is an XML-based open file format using an ASCII format, reading such files with MATLAB is easy. Here is an example of reading multiple XrdML files from a file directory, convert the files in text files, display the measurements together with standard mineral data from a XRD data base.

Second Edition of MDRES Released at SpringerNature

Today the 2nd Edition of MDRES was published at SpringerNature, now with the new title “Collecting, Processing and Presenting Geoscientific Information“. The book, with coauthor and designer Dipl.-Ing. (FH) Elisabeth Sillmann from BlaetterwaldDesign, aims at introducing students to searching relevant literature, reviewing and ranking published books and journal articles, extracting relevant information from the literature in the form of text, data, or graphs, searching and processing the relevant original data using MATLAB, and compiling and presenting the results as posters, abstracts, and oral presentations using graphics design software.

MATLAB experiment to simulate uncertainties of differences

MATLAB is a great tool to simulate error propagation. As an example we will use the software to estimate the uncertainty in the difference between the measures of two quantities A and B, based on their individual uncertainties and σA and σB. The experiment shows the error of differences in case the errors are either dependent or independent of each other.
