Hi guys

This might at first glance appear as a non-matlab question, but bear with me. This IS a matlab question and it is fairly urgent.

I am working on a textfile in latex and due to a slight case of computer meltdown, the whole thing appears to be wiped clear of information after rebooting. Yet the file is still the right size and I can scroll through it just as if the information was still there (have tried several programs incl. textpad and notepad), so I was wondering if Matlab could be used to retrieve any of the information that has been lost? I have tried a variation of textscan, textread, fread, etc, with no luck so far.

ANY help is much appreciated!

Difficult to say. You would want to fread() the file and look at the bytes that are there and see if there is anything useful.

Its just a whole heap of zeros. I have had a few other people take a look at it using various programs and they all seem to agree that it is empty. Sigh... Thanks for giving your thoughts on it though!

I've put in a feature request that the MATLAB editor have a hex mode, like my old favorite (now dead) code editor called Codewright. Such a feature would be useful here so you wouldn't have to write code to see the bytes. I hear SlickEdit has this capability. It sounds like the whole file has been overwritten with 0x00 or some other non-printable character (this would still let it have the same file size).
