From Theory to Practice Dina Katabi O Abari E Adalsteinsson A Adam F adib A Agarwal O C Andronesi Arvind A Chandrakasan F Durand E Hamed H . Such matrices has several attractive properties they support algorithms with low computational complexity and make it easy to perform in cremental updates to signals We discuss applications to several areas including compressive sensing data stream Aswin C Sankaranarayanan.
