textfiles

Hello all,

I would like to scan text of textfiles in Matlab with the textscan function. Before I can open the textfile with fid = fopen('C:\path'), I need to unzip the files first. The files have the extension: *.gz

There are thousands of files which I need to analyze and high performance is important.

I have two ideas: (1) Use an external program an call it from the command line in Matlab (2) Use a Matlab 'zip'toolbox. I have heard of gunzip, but don't know about its performance.

Does anyone knows a way to unzip these files as quick as possible from within Matlab?

Thanks!
