I checked in the following changeset:

  http://hg.savannah.gnu.org/hgweb/octave/rev/f217edac2c71

This change fixes the problem for me, so I'm closing this report.

Are you really using 3.3.52?

See how transpose of first matrix (y2) gets ignored:


> coeffb = y2 \ xmapped;
error: operator \: nonconformant arguments (op1 is 1693x50, op2 is 1x50)
> coeffb = y2.' \ xmapped.';
error: operator \: nonconformant arguments (op1 is 1693x50, op2 is 50x1)
> coeffb = y2.'; % forced assignment
> coeffb = coeffb \ xmapped.'; % OK!
