Fabián Before digging too deep into the libraries themselves, you may want to get the latest version of Octave from the repository. 3.6.3 is from a couple months ago and there may have been some code changes related to sparse matrices since then. Here is the graph at the time of 3.6.3: http://hg.savannah.gnu.org/hgweb/octave/graph/a95432e7309c From there you can move forward in the graph using the +60 button on the right side. Then use the browser search for "sparse". I'm seeing related changesets below. Whether any of those contain a fix, I'm not sure. If the problem persists, then write back and folks can help isolate the problem in the library or Octave. Dan # Fix Octave builds with SuiteSparse >=4.0 (bug #37031)6 weeks ago # Ensure sparse constructors have valid ridx and data indices even if they are zero matrices (bug #36104) # Special-case removing rows or columns from empty sparse matricesstable # build: Don't directly compile #included template code Sparse.cc, MSparse.cc5 weeks ago # configure.ac: Fix building of Octave with ancient versions of SuiteSparse (3.2.X) # when writing sparse matrices to MAT files, use nzmax of at least 1 (bug #36603) # error out when attempting sparse minimum solution and CXSparse is unavailable ------------------------------------------------------------------------------ Everyone hates slow websites.
