The step direction in DSDP is the solution to a set of linear equations. The cones used by DSDP compute the elements of the matrix and the right-hand side vectors. Any matrix that implements the Schur complement matrix interface can be used by DSDP. In addition to factoring a matrix and solving it, this interface also provides matrix assembly routines for the cones.
