A matrix is incoherent when L˜ n is small. See, for example, Donoho, Elad and Temlyakov (2006). With slight abuse of terminology, in this paper we shall call both Ln and L˜ n coherence of the random matrix Xn, the former for the case μ is unknown and the latter for the case μ is known.

WebCoherent plane-wave compounding (CPWC) enables high-frame-rate ultrasound imaging, but the imaging quality is mainly determined by the beamforming method. Covariance-matrix-based statistical beamforming (CMSB) was previously proposed for synthetic aperture ultrasound imaging, which provides notable improvements in resolution and contrast over … Weblaws of the coherence of a random matrix is to the construction of compressed sensing matrices. Compressed sensing is a fast developing field which provides a novel and …

For the mutual coherence of a single matrix, you can make your own function and implement it later in command line. Here is my function (I had used the convention X*X' for my purpose, you can use change it to X'*X) :-. WebThe use of incoherent electrooptical analog methods for performing matrix-vector multiplication has been investigated mathematically. A technique for encoding the matrix information on a two-dimensional binary optical transparency by means of an area modulation scheme is described.
WebThe matrix elements represent the elements of a positive semi-definite Hermitian matrix; they characterize the decohering processes and, as such, are called the noise parameters. … Various matrix completion algorithms have been proposed. These includes convex relaxation-based algorithm, gradient-based algorithm, and alternating minimization-based algorithm. The rank minimization problem is NP-hard. One approach, proposed by Candès and Recht, is to form a convex relaxation of the problem and minimize the nuclear norm (which gives the sum of the singular values of ) instead of (which counts the number of non zero singular values of ). This is an…
