Details:

This version initialize the outputs corresponding to inputs whose std is 0
as

 ind = (s > 0);
 retval = zeros(sz, class(x));

But this fails for a user-defined class, exept is the zero function is
overloaded too. But for a dataframe, this doens't make sense, as all the
meta-info would not be transmitted. OTOH, by properly overloading functions
like 'sum', this meta-inf is kept during the processing. I enclose a patch
where, if the input is an object, data which should be nulled are set from
standard assignment. This is less efficient, but permits to keep the
meta-inf.

Regards

Pascal
