How to use the OO features of Octave

[David Bateman]

Trying to use the OO features of 3.1.51, I fail on a very basic issue. I 
have a class directory "@myclass" with the constructor

function b = myclass (a)
 b.a = a;
 b = class (b, "myclass");
endfunction

When called I get error

error: class: invalid call from outside class constructor
error: called from:
error:   /home/adb014/nobackup/perso/octave/@myclass/myclass.m at line 
3, column 5

what is the issue with the above? Basically, I thought I might try and 
do some documentation for the OO could with examples, but am failing 
miserably at the moment.

Regards
David
