*
*Parameters: input
* IPMAT pointer to Matlab-m file.
* IFTRK pointer to the TRACKING file.
* IPRINT print level.
* NSKTRK number of records to skip on track file before tracking
* lines can be extracted.
* NBTR numbre of tracks.
* NDIM number of dimensions for problem.
* NREG number of regions for problem.
* MXSUB maximum number of subtracks in a line.
* MXSEG maximum number of segments in a line.
* NANGL number of direction for tracking.
* NBDR number of direction for volume normalization.
* NPLOTS number of plots.
* IPLOT plot number being processed.
* IPLP integer plot parameters.
* DPLP real plot parameters.
* DANGLT track directions.
* DVNOR track normalization factor for regional volumes.
