Fig. 7From: Computable performance guarantees for compressed sensing matricesa A simple example of a network tomography graph. W, X, Y, and Z are nodes in the network, and Path1, 2, 3, and 4 are the probing paths through which the packets are sent. b The sensing matrix corresponding to the graph shown in a. The rows and columns of the matrix represent probing paths and edges respectivelyBack to article page
