The unlet Command

The unlet command will delete the vectors listed as arguments.

unlet vecname [...]
The current plot is assumed, though the plot.vector notation is accepted. When the default scale vector is deleted, another random vector will become the default scale. The names can be ``all'', indicating that all matching vectors should be removed. If the vector name is ``all'', all vectors in the plot are removed, but the plot itself is not deleted. Giving ``all.all'' will clear the vectors in all plots (not very useful). To delete a plot, use the destroy or free commands.
