A matrix A ∈ C~(n×n) is called R-skew symmetric if RAR = -A. The least-squares solutions of the matrix inverse problem for R-skew symmetric matrices with R* = R are firstly derived, then the solvability conditions and the solutions of the matrix inverse problem for R-skew symmetric...

It is shown how the boundary element solution may be differentiated with respect to a design parameter without having to solve a second perturbed field problem. It is demonstrated that the small, full nature of the boundary element coefficient matrix makes the method cost-effective compared to the...
the solution of the LIP is unique, and the model parameters are given by multiplying thematrix inverseA−1with the datad. In the situationM>N, it becomes an over-determined problem that may have no solution. In situations

Regarding Theorem 2.1, the direct construction of an inverse operator K−1 is not possible and another solution of this problem should be found. To solve the problem of ill-posedness, it is convenient to introduce the definition of the best-approximation solution of Kx=y. Definition 2.2 K:...
