i have this large text file containing a matrix. This text file contains the non-zero entries of a very large sparse matrix
The first two columns indicate the position of the non-zero entry and the last column the actual non-zero value it self for example the matrix 1 0 8 0 0 5 6 0 0 is written in the text file in the form of 1 1 1 1 3 8 2 3 5 3 1 6 This is the standard [(row ,column), non-zero] entry format. i want PETSc to load this matrix from the text file i am not sure how to do that. What commands do I use? I am new to PETSc, so some detail in the explanation will be really helpful. Sincere thanks, Gaurish. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.mcs.anl.gov/pipermail/petsc-users/attachments/20101221/e9290949/attachment.htm>
