title: Is sparse matrix-vector multiplication available in Simulink/xPC?
body: <p>I am trying to make my control algorithm more efficient since my matrices are sparse.  Currently, I am doing conventional matrix-vector multiplications in Simulink/xPC for a real-time application.  I can not find a way to convert the matrix to a sparse one and perform that type of multiplication where it is compatible with xPC.  Does anyone have an idea on how to do this?</p>
