What Is... a Rip Matrix?
RIP matrices– shorthand for matrices which satisfy the restricted isometry property– appeared as a byproduct of Compressed Sensing; a method discovered by D. Donoho, E. Candès and T. Tao in 2004 with several applications in computer science. Besides their real world application, RIP matrices are interesting mathematical objects because, on the one hand, a random matrix has a negligible probabil...
متن کاملP-value: What is and what is not
The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.
متن کاملWhat a Classical r-Matrix Really Is
Abstract The notion of classical r-matrix is re-examined, and a definition suitable to differential (-difference) Lie algebras, – where the standard definitions are shown to be deficient, – is proposed, the notion of an O-operator. This notion has all the natural properties one would expect form it, but lacks those which are artifacts of finite-dimensional isomorpisms such as not true in differ...
متن کاملThe least-square bisymmetric solution to a quaternion matrix equation with applications
In this paper, we derive the necessary and sufficient conditions for the quaternion matrix equation XA=B to have the least-square bisymmetric solution and give the expression of such solution when the solvability conditions are met. Futhermore, we consider the maximal and minimal inertias of the least-square bisymmetric solution to this equation. As applications, we derive sufficient and necess...
متن کاملA new Approximation to the solution of the linear matrix equation AXB = C
It is well-known that the matrix equations play a significant role in several applications in science and engineering. There are various approaches either direct methods or iterative methods to evaluate the solution of these equations. In this research article, the homotopy perturbation method (HPM) will employ to deduce the approximated solution of the linear matrix equation in the form AXB=C....
