Details:

If your cell array contains matrices with NA (not NaN), and you save it as
ascii (is this the default?),  you can not load it in again.

Here is a simple example

H = cell(2,1)
H{1} = ones(2,3) - j * ones(2,3) ;
zz = ones(2,3) ;
zz(2,:) = j *[NA, NA, NA] ;
H{2} = zz ;
save bad H
load bad


This fails with the error:
error: load: failed to load matrix constant
error: load: trouble reading ascii file ''
error: load: reading file 
error: load: cell array element had unexpected name
error: load: failed to load cell element
error: load: trouble reading ascii file 'bad'
error: load: reading file bad
error: called from:


I have run across several bugs in trying to convert a large complex matlab
project into octave.  For some reason some of the converted Matlab code is
filling some columns of my matrices with NA's instead of NaNs.  I am now faced
with the prospect of flushing out the NAs and replacing them with NaNs to get
this to work.
