[Gmsh] How to only print lower triangle of symmetric matrix with print[A] in getdp

[moritz braun]

Hi Michael

Here we go!

my .pro file is attached!

In order to use them in my python based scripting
I also had to convert them  to matrixmarket format
for which I used
the attached script

My pet peeve with getdp is that i only does simple linear
tetrehedral elements in 3D in contract to gmsh that goes up to fourth order!

regards

Moritz
