inverse of sum of matrices
Posted:

Hello, I need help. Let "A" be such a square matrix:
A=[W+aM]
where "W" and "M" are symetric matrices and "a" is any real scalar. I am interested in inverse of "A". I want to express inv(A) in terms of "a", where "a" is not included in an inverse matrix expression. If there is not exact expression, a good approximation can also be fine. Thanks a lot. Best regards.
