Yeah, you're right that for analysis of FEM data it's more profitable to use
for example Paraview.
However, I want to use Matlab not for the analysis of data but for the
figures. I've got some points and lines
that I want to add on output figures. I can do these thing in Matlab easily,
however, I need to somehow plot the
original solution. I'm just interesting if there is a simple way to do this.
I don't know of one. All of the visualization formats are complicated, so
unless you can find a VTK or GMV or OpenDX reader for Matlab, it's going to be
difficult. As I mentioned, the issue is made complicated by the fact that a
mesh isn't just field data on a regular xyz grid, but also where the vertices
are, how vertices connect to each other in cells, etc. Fields can also be
discontinuous, in which case you have multiple values at the same point. All
of this makes it difficult to define an "easy file format" that is then easy
to read from Matlab.
If all you want is add some points and lines to a picture, then I'd say you'd
be better off creating a VTK file that contains these points and lines, and
make Paraview of Visit plot both the original solution file and your
hand-written one.
