Sparse representation of solutions of Kronecker product systems
Sadegh Jokar, Volker Mehrmann · arXiv (Cornell University) · 2009
Three properties of matrices: the spark, the mutual incoherence and the restricted isometry property have recently been introduced in the context of compressed sensing. We study these properties for matrices that are Kronecker products and show how these properties relate to those of the factors. For the mutual incoherence we also discuss results for sums of Kronecker products.
