It seems that all of the following work as I would expect

  x = logical (eye (2))
  class (x)               => logical

  class (x(2,2))          => logical

  x(2,2) = logical (0)
  class (x)               => logical

  x(3,3) = logical (0)
  class (x)               => logical

  x = logical (0)
  class (x)               => logical

  class (x(1,1))          => logical

but

  x(2,2) = logical (0)
  class (x)               => double

which is clearly wrong, and prevents a solution like

  x = logical (0);
  x(m,n) = logical (0);

from approximating

  zeros (m, n, "logical")

Is this what you meant, or did you notice some other problem with
indexing logical values?

In any case, the conversion to double is a bug and I will fix it.

Thanks,
