[petsc-users] Saving Vecs/Mats in HDF5 and visualizing in Matlab

[zakaryah]

Hi Yuyun,

I'm not sure exactly what you want to do but I use Matlab to work with and
visualize HDF5 files from PETSc all the time.  Matlab has h5info and h5read
routines, then I visualize with my own routines.  Is there something
specific you need from Matlab?
