We call all our users, who upgraded his Matlab version to R14SP1+ (i.e. SP1, SP2 or SP3, see Mathworks web site for more details) to upgrade his URAPIV.M from the download site: http://sourceforge.net/projects/matlabpiv
URAPIV.M is now a self-inclusive function, that contains all the necessary utility functions (ReadImdir() and QuiverM()) inside, sharing the variables without calls-by-reference. Moreover, ReadImDir() is updated to read more image formats: JPEG, TIFF, BMP (and can easily be extended for more formats) and also reads sequential lists (from High-frame-rate PIV or high-speed PIV or cinematographic PIV) and also from cross-correlation cameras (a usual _b.xxx and _c.xxx convention for the base and cross frames).
