Description
Write the observed points to a VTK file.
Usage
writeObservedLocationVTK(move.dat, mkde.obj, description, filename, control)
Arguments
move.dat |
A move data object created with |
mkde.obj |
An MKDE object created with |
description |
A text description for the file header |
filename |
A string for the path and file name |
control |
A list for finer control |
Details
