Running means are very popular to smooth noisy time series. Unfortunately, they have unpleasant side effects. Here is a MATLAB example to demonstrate the effect of running means.
Create Publishable Graphics with MATLAB, Part 1
The graphics of MATLAB have been greatly improved since the very rustic plots of the early 1990s. In contrast to previous editions, in which all the graphics were edited by designer Elisabeth Sillmann (blaetterwaldDesign) with Adobe Illustrator, the majority of the graphics of the 4th edition of MRES were not processed after being exporting from MATLAB. Here is the script for creating a variant of Figure 4.9 from MRES.

Cross Recurrence Plot Toolbox
Here is another great MATLAB-based website, the one about recurrence plots by my colleague and long-term collaborator Norbert Marwan from Potsdam Institute for Climate Impact Research (PIK). Recurrence plots for the analysis of complex systems are popular in many fields such as climate science, flow mechanics and medicine. Continue reading “Cross Recurrence Plot Toolbox”
About me
Here is a short outline of my research and teaching at the U Potsdam, Germany, and elsewhere, with emphasis on the use of MATLAB in earth sciences.
The MATLAB® / LEGO® MINDSTORMS® Model of a Moving Satellite
This was one of my first MATLAB® / LEGO® MINDSTORMS® projects: the model of a moving satellite. Three exercises have been developed from this, which I will shortly provide in the member area with solutions.

The MATLAB® / LEGO® MINDSTORMS® Shopping List
So it all started. I was an invited speaker at the MATLAB Expo 2016 in Munich with a lecture on “Dust storms, blackouts and 50°C in the shade: with MATLAB in the cradle of humankind“. One of Keynote Lectures was held by Dr. Rainer Stetter of ITQ, “Industry 4.0 – Risks and Opportunities”, who talked, among other things, about the European Hi5 Hackathon 2016 with MATLAB and LEGO MINDSTORMS. I wondered how I could use the connection of MATLAB and LEGO MINDSTORMS, using the hardware support of The MathWorks in my shortcourses on geoscientific data analysis and future editions of the textbooks.

Calculating the Continuous 1-D Wavelet Transform with the new Function cwt, Part 1
In MATLAB R2016b, the function to calculate a continuous 1D wavelet transform has been replaced by a new function, unfortunately with the same name. Here is a great example why I think that this blog is very useful: Here I can let you know how I would modify the script of Chapter 5.8 of MRES and ask for your comments on it, long before the 5th edition of MRES will be published.
All about the Books
For those of you who do not already know the two Springer books, here is a summary of the books, the available editions, the electronic supplement and errata files.
