Subject: Octave cannot read ASCII NaN's
--------
Bug report for Octave 2.0.13 configured for i586-pc-linux-gnulibc1

Description:
-----------

This (and previous) octave distributions cannot read files with ASCII
NaN's in it.

When octave saves the file in octave's binary format NaN's are no problem.
However when using the ASCII mode it is.

Below is a simple script which reproduces the problem and gives the following
error messages:

error: load: failed to load matrix constant
error: load: reading file test.oc
error: evaluating index expression near line 10, column 1

Hope this helps to improve an already great package!

Michel.


Repeat-By:
---------

Startup octave

a=[1 2 3; 4 5 6]
a(1,2)=NaN;
save -binary test.oc
clear
load test.oc
a
disp('So far so good! Now for the ascii mode.');
save -ascii test.oc
clear
load test.oc
disp('See error message in Description section');
