Dear Anup, > 1. if the way of writing the sparse matrix on a .txt file is appropriate > for post-processing in matlab, if not, please suggest > a way; >
There are three print functions in the deal.II SparseMatrix. As explained in the documentation <https://www.dealii.org/developer/doxygen/deal.II/classSparseMatrix.html#af38b1c3e6200698c3d9ea5577436c61c>, you've chosen one that dumps the entire matrix with all zero entries not in the sparsity pattern printed as well. This function <https://www.dealii.org/developer/doxygen/deal.II/classSparseMatrix.html#a57ee42a70d603759e17b8a204af3c4d5> is probably the one that you want. > 2. how should I make matlab understand the size of the sparse matrix and > arrangement of the elements. > This is outside of the scope of this forum. However, I'm sure that with the correct printing format, how to deduce the sparsity pattern of the matrix will become more apparent to you.
