Details:



I am not sure whether this is expected behaviour, 
but I cannot seem to find mention of it in the docs :


>> a = randn (4);
>> b = randn (5);
>> save -binary prova a
>> save -binary -append prova b
>> clear all
>> load prova
>> whos

   Attr Name        Size                     Bytes  Class
   ==== ====        ====                     =====  ===== 
        a           4x4                        128  double
        b           5x5                        200  double

Total is 41 elements using 328 bytes

>> save -z -binary provaz a
>> save -z -binary -append provaz b
>> clear all
>> load provaz
error: load: trouble reading binary file 'provaz'
