The file ID_012204.zip contains Matlab code for producing original and sampled data used in adaptive C++/PETSc code. To be able use Matlab's code one need download data files pval.txt mtype.txt
for object with ID=012204 from online repository https://uwcem.ece.wisc.edu/MRIdatabase/
All inp-files can be visualized in paraview.
GeomTest1.zip contains following files which were used for generation of data on 3 times locally refined mesh for Test 1: epsref3.m (file with exact epsilon), sigmaref3.m (file with exact sigma), ref3.inp (file with finite element mesh).
MeshesTest2.zip contains following files which were used for generation of data on 3 times locally refined meshes for Test 2: epsref3.m (file with exact epsilon), sigmaref3.m (file with exact sigma), ref3.inp (file with finite element mesh )
Test1noise10.zip contains final results of reconstructed epsilon on different refined meshes. Test2noise10.zip contains final results of reconstructed epsilon obtained on different locally refines meshes.
