Reading Tar Files In Matlab

I have a link: https://www1.ncdc.noaa.gov/pub/has/HAS011460917/

There are a list of tar files

In the tar files, there should be hourly precipitation amounts and they should be designated by location (longitude or latitude or pixels).

I am told that it is possible for Matlab to import this data and organize (tabulate or analyze) the precipitation amounts according to location for each file.

I started with

filenames = untar('C:\Users\Joseph\Documents\NWS_NEXRAD_NXL2SR_KOKX_20100203140000_20100203145959.tar')

Then a few gz files would appear in the Current Folder window.

I would then write something lke

files = gunzip('KOKX20100203_145516_V03.gz')

This will produce a file with a name KOKX20100203_145516_V03

When I click table, it shows up in unicode.

So currently, I am even unable to get a legible table, let alone tabulate results according to location.

If anyone is able to help in any way, at any level (not necessarily even organizing by location, but just even reading or opening), that would be great.

Thanks,

J
