PIVlab direct download

Hi everybody! For those who do not want to register on the Matlab website in order to download PIVlab, I added a direct link to the zip archive (see the column on the right side). You can also click here to get the zipped PIVlab toolbox:

There were no updates of PIVlab since quite a while. The reason is that I am currently not working with particle image velocimetry after I finished my PhD. That is a pity. But the good thing is that I converted one of my other hobbies into a profession: Since 2014, I am working as a mechanical design engineer at TobyRich GmbH. Over there, I am responsible for the design of fixed-wing drones, which is - similar to doing PIV - a lot of fun.
I am sorry that (in most cases) I can not react to your emails or forum entries. My life is currently filled up with too many other things that require my attention.
Success with your analyses!!

PIVlab 1.41 - now 10x faster processing!

Recently, Sergey, a Junior Researcher at the ISSP RAS contacted me and told me that he found a way to make PIVlab (specifically the DFT window deformation part) much faster. He rewrote PIV_FFTmulti.m in a way that doesn't use 'for loops' anymore. The result is a heavily improved processing speed of PIVlab. I tested MATLAB versions 2011a, 2014b and 2015a. The speed was improved by a factor between 7.9 and 10.6 for a 'standard analysis' with three passes. Improvements up to a factor of 30 seem possible.

Thanks a lot Sergey, this will save a lot of people a lot of time!!

PIVlab 1.4

I just uploaded the 1.4 release (compatible with R2014b and earlier). Download it here:
PIVlab1.4

PIVlab is now also available as 'App'. You can install it in Matlab by double-clicking on 'PIVlab.mlappinstall'.

Features:
MATLAB R2014b compatibility (yaay!)Backwards compatible (the oldest version I could test is R2011a, but it should also work with much older releases)Improved speed of FFT and the spline window deformation (due to some changes in R2014b)Speed testing tool (run Testspeed.m to benchmark your hardware)New default colormap ParulaPackaged app makes installation and execution simplerSeveral minor fixes / improvements

Working on r2014b release...

I am making progress with the r2014 update of PIVlab, several incompatibilities are fixed already. This requires some extra attention, because PIVlab must stay compatible with earlier Matlab releases. I think that I will be ready to post a beta release of PIVlab 1.4 at the end of this week.

Donation complete!

Hey, we just reached the goal of 134 Euros! Thanks! I just downloaded MATLAB and will soon start working on PIVlab v1.4 ! I already noticed that R2014b is quite fast in comparison to previous releases.

Matlab R2014b compatibility donation

Mathworks changed a lot in their latest Matlab release (R2014b), making it incompatible with PIVlab 1.35 (and probably many other toolboxes). I'd like to make it compatible, but I need access to Matlab R2014b to do the necessary changes and to find all the issues.

I already contacted Mathworks, but they are not willing to support me with an extended trial version. I am not working at the university anymore, therefore I don't have access to any academic licenses.

A "Home license" of Matlab + Image processing toolbox is 134 euros.

If you're interested in this update, then please donate as much or as little as you like. But please note that your donation does not guarantee that I will succeed in making the necessary changes. You do not receive any additional rights. Everything I do is just voluntary - just like your donation.

If I manage to receive 134 Euros until the 15. march 2015, I'll buy the license and start trying to make PIVlab compatible. If I do not …
