Oops, never mind, I misunderstood what I was reading.

Is this the right fix? Shouldn't S < D work if s is sparse and D is diagonal? I think the right fix is to extend the comparison operators to diagonal matrices. That's the direction I was looking into fixing this.

Fixed in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/c2e8c9d9e284). You will need to build from the Mercurial sources in order to see this change or wait until release 3.4.1. Instructions for downloading the source are available at http://www.gnu.org/software/octave/download.html.

Executing

>svds(speye(10))


results in

error: svds: mx_el_gt: nonconformant arguments (op1 is 6x6, op2 is 1x6)
error: evaluating argument list element number 1
error: called from:
error: /home/dedoslav/octave-3.4.0/scripts/sparse/svds.m at line 195, column 9

This is new to 3.4.0, the 3.2.x series works as expected.
This is for 3.4.0 compiled from source on 32-bit Ubuntu with all default settings (./configure, make, ./run-octave) and all dependencies satisfied.
