Follow-up Comment #8, bug #51437 (project octave):

Other languages which are far stronger in statistics, such as R, return NaN
for the case of empty matrices.  Sample R code,

x = matrix (c(1), nrow=3, ncol=0)

It seems more useful mathematically for Octave to return NaN in these cases
rather than occasionally NaN and occasionally a dimensioned empty matrix, even
if there is a rule for when "occasionally" occurs.
