indexing operations in 2.1.39 |

I'm having trouble with my sparse code with
octave-2.1.39.
The code compiles, but Indexing operations give:
address@hidden /usr/src/octave-forge/main/sparse
$ /usr/local/oct-2.1.39test/bin/octave-2.1.39.exe -q
octave-2.1.39:1> s=sparse(eye(2));
octave-2.1.39:2> s(:)
error: can't perform indexing operations for sparse type
I have dug around, and found that indexing operations
no longer call "do_multi_index_op", but now call
the method "subsref"
I have got sparse to work correctly by adding the method:
octave_value_list
octave_sparse::subsref (const std::string type,
const SLList<octave_value_list>& idx,
int nargout)
{ return do_multi_index_op( nargout, idx.front()); }
$ /usr/src/octave-2.1.39/src/octave.exe -q
octave:1> s=sparse(eye(2));
octave:2> s(:)'
ans =
1 0 0 1
MY QUESTION IS:
Is this the correct use of subsref?
Is this the right way to do this?
There is no documentation on subsref (that I could find)
so I'm not sure what it's supposed to do.
Thanks
Andy
