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!! Download: http://www.mathworks.com/matlabcentral/fileexchange/27659-pivlab-time-resolved-particle-image-velocimetry--piv--tool
