3.2.1.16 Inverse matrix The inverse matrix of A is that matrix A−1 that satisfies the matrix product AA−1=I. The inverse matrix of A is computed as (3.1)A−1=adjA/detA Example: let A be a square matrix of order 3 given by A=[1−21132201] In accordance with the resu...
In this paper we prove that the inverse mean problem of geometric and golden means of positive definite matrices $$ left{ begin{aligned} & A = X# Y & B = frac{1} {2}(X+X# (4Y - 3X)) end{aligned} right. $$ is solvable (resp. uniquely solvable) if and only if $ A leq{sq...

The general crashing problem is caused by the fact that you use complex LAPACK routines when you don't have complex inputs or outputs. So you are copying stuff into and out of NULL pointers. E.g., 테마복사 plhs(1) = mxCreateDoubleMatrix(m,n,1) ...
An n × n complex matrix A is termed Re-positive definite (Re-pd) if the real part of x Ax is positive for every nonzero complex n-vector x . This paper is concerned with constructing complex Re-pd matrices and solving the following matrix inverse problem: Given complex matrices X and...
