The symmetric,positive semidefinite,and positive definite real solutions of the matrix equa-tion XA=YAD from an inverse problem of vibration theory are considered.When D=D^T the necessary and sufficient conditions for the existence of such solutions and their general forms are derived.高校应用数学...
The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
