My talk on the MATLAB EXPO 2019 in Munich (July, 2nd)

Image
I will be giving a talk on PIVlab on the "MATLAB EXPO 2019 Deutschland 2. Juli | München".
The link to the agenda is here: https://www.matlabexpo.com/de/2019/agenda.html
Maybe this would be a nice chance to meet...?


Update PIVlab 2.02

Image
Changes:New derivative: Vector direction (use HSV colormap for best display performance)Save and load PIVlab masks, also load masks from previously saved session filesMask transparency can be set, can also be used to make the mask invisible (100% transparent)Tool tips display help and information for all buttonsKeyboard shortcuts enables the user to work more efficientlyList with all keyboard shortcuts can be accessed from the help menuFixed a zoom bugWhen smoothing data, some extra information on what actually happens is now displayed in Matlabs command windowLoad external mask(s) improvedRemoved some unnecessary data in *.mat file export

Donations complete - thank you!

As my personal Matlab license was pretty old, I was asking for donations for renewing my license during the last 365 days. It is important that I have a recent Matlab version to keep PIVlab alive.

And today, the donations reached 99.37 EUR, and I just renewed my Matlab license :-D Thank you! The new Matlab release even makes PIVlab 10.24 % faster!



Update PIVlab 2.01

Image
New features:
The user can now load time-resolved masks instead of single masksThe user can now select the color of the color legend labelThe PIV settings are now checked automatically, and a warning is given if unusual parameters were selected 
Bug fixes: Loading session files from older PIVlab versions is now possible (forum post)Fixed bug where the tools panel showed slightly incorrect data sometimes (forum post)Fixed bug where a warning message was displayed too often (forum post)




Major update: PIVlab 2.0

Image
In the past, it happened quite often that the user interface of PIVlab was not displayed correctly on Mac computers. So I decided to completely reprogram the user interface "by hand" (that means without using Matlabs built-in GUI IDE called "GUIDE"). It was quite some work, but I believe PIVlab is now future-proof and easier to maintain. GUIDE was crashing pretty often in the last months, making enhancements very difficult.



So these are the changes:GUI rewritten from scratch, should now be displayed correctly on all operating systemsAdded prefernces in the menu: You can change the panel width of the UI if the UI elements are not scaled correctly.Changed "Load external mask": You can now make masks outside of PIVlab and save them as black-and-white TIFs. When you import these masks, then white will become a masked area and black is non-masked area.Added TECPLOT file format for export.Background subtraction GUI only worked with grayscale images --> fixed…

Order a book about PIVlab!

Image
I still have a number of my dissertation books, it contains an extensive chapter on PIVlab. You can order a copy for 3 Euros + shipping (the money will be used to add to my Paypal money pool which will one day be used to renew my Matlab license).



The beauty of PIV cross-correlation!
