docpivmat displays the start page for the PIVMat toolbox in the help
browser. In Matlab 7.3 and before (R2006), typing "doc pivmat" had the
same result. However, since Matlab 7.4 (R2007a), the doc function
changed, and this feature is not available anymore, so you have to
use docpivmat instead.
docpivmat function_name displays the documentation of function_name
in the help browser. In Matlab 7.3, this is strictly equivalent to
Published output in the Help browser
