Hallo!
Title pretty much says it all... none of the mtx objects help files seem to be in the builds. I haven't updated my dev layout in a while but they're present in externals/iem/iemmatrix/doc and abs here.
Okay, I have added iemmatrix to the buildsystem - it should work now (and also much more iem externals)
Also having the creation issue when using the symbolic representations of operators, e.g. mtx_<= will not create until mtx_le has been. I
The problem is with the single object externals, that the aliases don't work (mtx_<= is an alias for mtx_le I guess) - so we would have to make wrapper pd-patches ...
LG Georg
