8. Обратная матрица

What is an inverse matrix? How do you find an inverse matrix? Which matrices have an inverse matrix? What is an adjoint matrix (also known as a conjugate matrix or reciprocal matrix)? What is the algorithm for finding an inverse matrix? We'll explore these questions in detail today using an example with a step-by-step solution. This is used here: 6.
