Hi, I have searched for a solution to this problem and have'nt found any info.
I am using dlmread to read a .dat file. This works fine the first couple of times, but then on the third or fourth attempt, the following error occurs:
''Mismatch between file and format string.Trouble reading number from file (row 1, field 2)==> ¦ÿ ''
To check the .dat file, I then try and open it using openoffice. It opens but not as normal- numbers appear as code.
Is it possible that using dlmread is altering the source file? Thanks M Green

I don't see how it could, at least not in 2008b. dlmread is a .m file that you can examine; it uses fopen() to open the file in default reading mode, and textscan() to read the file.
