Not right now, but it is on the todo list to allow the Symmetric type to wrap sparse matrices. To be really useful, it would also require some methods that could exploit the symmetry, but that would probably come along the way.
Maybe you already know that, but for positive definite sparse matrices you can use cholfact when solving a system of equations. 2014-07-09 13:16 GMT+02:00 Eduardo Lenz <[email protected]>: > Hi. > > I am new to Julia, so I apologize if this is a well known issue or if it > has been discussed before. > > I work with symmetric sparse matrices and I would like to know if its > possible to > store just the upper (or lower) part of a matrix and inform Julia when > using this matrix to solve a linear system (using lufact, for example) or > when making simple operations, like sparse*dense. > > I don't know if there is a flag or something like a view for informing > Julia about this. > > Thank you. > -- Med venlig hilsen Andreas Noack Jensen
