## tics(axis,[pos1,pos2,...],['lab1';'lab2';...])
##
## Explicitly set the tic positions and labels for the given axis.
##
## If no positions or labels are given, then restore the default.
## If positions are given but no labels, use those positions with the
## normal labels.  If positions and labels are given, each position
## labeled with the corresponding row from the label matrix.
##
## Axis is 'x', 'y' or 'z'.
