Hey all, I am currently working on a large matrix, and I already have a specific eigen value that I want to use in order to find out its corresponding eigen vector. Is there an easy way to do so? I have tried with linalg.solve(a, b), where I put a as the Matrix A - eigen value* unit

I have tried with linalg.solve(a, b), where I put a as the Matrix A - eigen value* unit matrix, and b as the zero matrix. But the solution returned is a zero matrix, which I really find disappointing. So if you're trying to solve (A - \lambda I) x = b, try appending an extra row to your
