fread bug in octave 3.8.0?

[Petri Piila]

Dear All,

Is there possibly a bug related to function fread in octave 3.8.0 or is this 
just octave os x problem (I’m running on 10.9 Maverics).

Demonstration :

First I save a matrix with fwrite and the try to read it with fread.

a = ones(4,4);
f = fopen(“frtest”,”wb”);
count = fwrite(f,a,”double”);
fclose(f);

Now count is 16 as expected.

f = fopen(“frtest”,”rb”);
[b,count] = fread(f,[1,Inf],”double");
fclose(f);

This works in 3.6.4 but now gives count = 128 and size(b) = [1 17]. First 
sixteen values are right and the last one is zero. Now count seems to be in 
bytes as 128/8 = 16

If I force count to 16 by using [1,16] or [4,4] instead of [1,Inf] I get count 
= 128 as before  and matrix b is of size 16 or 4,4.

So, is it intentional that count in fread is now in bytes and why the extra 
zero in result if I use Inf which used to be handy if I don’t know the size 
beforehand?
