The process is typically done within each probe, not across the entire
matrix, but it depends a bit on the parameters given, at least for
heatmap and heatmap.2.  Reading the help pages for heatmap and heatmap.2
will be helpful here.  I generally recommend that before someone uses a
new function in R or bioconductor, that he read the help page, although
I have been guilty of not doing that myself at points.
