Convert dSPACE ControlDesk measurement to MATLAB timeseries that can be used in Simulink
- dSPACE ControlDesk can export measurements to mdf4 files or mat files
- mat file exports can be converted to timeseries with this MATLAB script
- The timeseries can then be imported into Simulink with the ‘From Workspace’ blog
- Multiple signals can be imported at once
Example output:
>> import_dspace_mat_to_simulink_ts --Imported dSPACE mat file C:\Users\Nicolai\Nextcloud\foo.mat into workspace variable dsp_ts --Time: 0.000000 s to 42.399572 s, 423980 steps --2 variables are in dsp_ts: 'In1' 'In1_1'
Automatically convert videos in Powerpoint file (pptx) to a different format
I have been trying to convert a lot of embedded videos in pptx files to a different format lately due to compatibility issues on some systems, but have not found an easy and fast way – so I wrote this bash script.
The goal was to have a pptx with videos that can be played using Powerpoint 2010 or later on Windows as well as OS X without plugins. That seems to only be the case for MPG videos (mpeg1video codec).
To convert videos in a presentation
- make sure that ffmpeg and a zip/unzip application is installed (ffmpeg can easily be replaced by avconv, but avconv somehow could not convert some files that were no problem for ffmpeg during my tests)
- download the bash file and make it executable
- edit the options at the beginning of the file, if you want to (mainly video output format and bitrate)
- Change to the directory with the pptx file(s) and start the conversion with /path/to/pptx_video_convert.sh myPresentation.pptx
- Check if everything worked by looking at myPresentation_converted.pptx or the logs
