[Gretl-devel] bread: bug with zero-element matrix inside bundle

Hi, I stumbled across the following bug in the MPI context, but it turns out it doesn't have anything to do with MPI. See: <hansl> bundle b = null matrix m = zeros(2,0) eval nelem(m) err = mwrite(m, "mcheck.mat", 1) print err # re-load matrix m2 = mread("mcheck.mat", 1) # works print m2 # correct info ("is empty") # bundle wrap matrix b.m = m err = bwrite(b, "bcheck.xml", 1) # seems to work bundle b2 = bread("bcheck.xml", 1) # data error eval $error </hansl> Seems the bread() function is not capable of handling the case of cols="0" (or rows="0") inside the xml-represented bundle. thanks sven
