This means that the column vector of unknowns x is found as the inverse of matrix A multiplied by the column vector b. So, if we can find the inverse of A, we can solve for the unknowns in x. For example, consider the following three equations with three unknowns x1, x2, and x3...
Authored by two experts in the field who have been long-time collaborators, this monograph treats the scattering and inverse scattering problems for the matrix Schrdinger equation on the half line with the general selfadjoint boundary condition. The existence, uniqueness, construction, and ...

It will often be the case that given a square matrix A, there will be a square matrix B such that AB = BA = 1. A matrix B with this property is called the inverse of A and is given the name A−1. If A−1 exists, it must be unique. The proof of this statement is simple...

The matrix Sturm–Liouville equation on a finite interval with a Bessel-type singularity in the end of the interval is studied. We consider inverse problems by the Weyl matrix and by the spectral data for this equation. Constructive solutions, based on the method of spectral mappings, are ...

Here is a synopsis of the paper. In Sect. 2 we show how the all-at-once approach for the solution of (1.2) leads to a Sylvester matrix equation. We discuss the incorporation of the boundary conditions for the matrix equation formulation in Sect. 3. In particular, in Sect. 3.1 we ...
