How can I import asc.gz files into matlab?

I need to get files from this directory: <ftp://sidads.colorado.edu/pub/DATASETS/NOAA/G02156/24km/2011/> into MATLAB however when I use URLREAD, it incorrectly reads in each file. Instead of reading in what should approximately be a 6400x6400 array, it reads in a supposed "1x24331" dimensional array something like this when I open up the variable: ')>N'

Use gunzip after you have downloaded the file but before you read the content.

Thanks Walter. I guess since URLREAD hasn't been working to import my data, how would I get the data into MATLAB before trying to unzip it?

Walter- I think I got it. Thanks again for your help.

[Walter Roberson]

ftp() instead of urlread() I would think.

How can I access the contents of .gz files with matlab

[Walter Roberson]

gunzip the files.

There is no direct facility in MATLAB to access individual files within a .gz archive.

If you know a bit of Java, it is possible to place calls to appropriate java routines.
