Another point (which was my original one): the names are not saved when 
a matrix is returned from a function.
If I transform your script into a function, and call it from a script 
the saved matrix has no row/col saved.

function matrix nothing (scalar value)
   m = I(value)
   if value = 3
     string cnames = "name1 name2 name3"
     string rnames = "name4 name5 name6"
     colnames(m, cnames)
     rownames(m, rnames)
     print m
   return m
end function
