Re: NaN

[Paul Laub]

Matt, 

Instead of fscanf(), you might try fgets() followed by str2num(). The
following lines work for me even when file.txt contains a NaN. (I am
using Octave 2.1.57 running on Cygwin and Windows 2000.)  This is not
likely to be an efficient method, but it might suffice.

fid = fopen("file.txt", "r");
str = fgets(fid);  # read one line from the opened file
row_vector_of_data = str2num(str); 

Hope this helps,
