LabPlot

@blindbunny

#LabPlot isn't exactly an open-source #MATLAB, but it is a an open-source and cross-platform tool for visualizing and analyzing data.

It focuses on creating interactive scientific plots and offers features like curve fitting, Fourier and Hilbert transforms, data manipulation, and live data support.

Computing with e.g. #Python, #R, #Maxima is also possible with interactive notebooks available in LabPlot.

You can see a list of LabPlot features here:

Terry Pratchett gave us octarine - the magical 8th colour of the spectrum, visible only to wizards and of course cats 🐱. UC Berkeley researchers have discovered "olo" - a real colour 🎨 that exists outside standard human vision… so far visible to only 5 people in the world! ✨

James Fong and colleagues used Psychtoolbox (the MATLAB toolbox that I owe my job too!) to control their RGB projector during the colour matching experiments.

Started with fft() for quick and dirty noise colour estimation in our biological motion power law work. Alas more data doesn't make it more accurate 📊 Not ideal when chasing subtly divergent movement signatures in Parkinson's and Autism. #MATLAB #MATLABambassador
We talked about noise colour (purple, blue, white, pink, red, black, i.e. α [-2,-1,0,1,2,3] when 1/f^α) way back in October: x.com/dagmarfraser/status/1846

X (formerly Twitter)Dagmar Fraser @dagmarfraser.bsky.social (@dagmarfraser) on XMaking all the right noises... MATLAB has wgn for White (Gaussian) Noise and pinknoise for Pink.. The power spectral density (PSD) of Pink is 1/f and so drops off as f increases (-10dB/dec as pictured). #MATLAB #MATLABAmbassador 1/10

Yes, I am intrigued by #Julia as a response to the #Matlab crisis.

Can you give a good place to start? (Basic tutorial, language definition, best IDE / package management system?)

My specific targets are
(1) large vectorized computations, preferably (1a) automatically GPU'd when possible and
(2) hardware control of (2a) arduino devices (access as sending characters over a serial port is fine) and (2b) online (at speed) video processing and storage, including camera hardware signaling.

Alternatively to (2), I have considered #BonsaiRx. Really good would be having a way of linking Julia with BonsaiRx (which does video well, but not the other task-control stuff).

#MATLAB in Teilen immer noch down: Seit über einer Woche hat die Programmiersprache/Berechnungsumgebung nun schon mit einem #Ransomware-Vorfall zu kämpfen - was ziemlich übel ist, weil nicht nur die Online-Anwendungen, sondern auch interne Mitarbeitersysteme betroffen waren. Und wenn man darüber nachdenkt, dass weltweit ca. 6.500 Unis das Tool nutzen, kann man sich die Auswirkungen auf die Forschung durchaus vorstellen.

#MathWorks server issues have persisted for days, affecting licensing and downloads. This highlights how dependent many academic workflows are on proprietary systems.

Consider alternatives that remain available regardless of vendor status:

🔹 Julia – built for numerical computing
🔹 Python – widely used, with strong scientific libraries

Both are open-source and resilient.
