Description

Write the MKDE to a XDMF files.

Usage

1
writeToXDMF(mkde.obj, fname, nodat="NA", cumprob=FALSE)	

Arguments

mkde.obj

3D MKDE object created with initialize3DMKDE and density initialized with initializeDensity

fname

The path and base file name for output XDMF files

nodat

A no data character string that will be written in place of no data values.

cumprob

Indicate whether to write the voxel probabilities of cumulative probabilities.

Details

This function writes XDMF XML wrapper and binary data file.

Value

No value is returned
