Invalid matrix while using str2num on large data sets

When using str2num on a matrix of size 1000x70 my code works. This means I must procees many...many data files. I used the UNIX CAT fuction to create one large data file from many small data files. Now when I use the str2num on the large matrix of size 10000x700 it returns an empty matirx. If I process each file independently the code works. How can I get around this str2num problem?

R2008b, Linux-64, it worked for me on a considerably larger matrix.
Which release are you using, which OS, and 32 or 64 bit?
My first thought would be that you are running out of memory.

str2num uses eval to convert the string. It is not a good idea to use this for the conversion. I suggest to use fscanf instead.
