Note: We cannot find the inverse of a matrix if the determinant of the given matrix is zero (0), i.e., the matrix is singular.Below is a program to find the inverse of a matrix of order 3x3 in C++. We have used an array for storing the matrix for simplicity....
How to find the inverse of an elementary matrix? Let A = \begin{bmatrix} 1 & 2 & -4\\ 0 & 1 & 2\\ -1 & 2 & 0 \end{bmatrix},\; C = \begin{bmatrix} 0 & 4 & -4\\ 0 & 1 & 2\\ -1 & 2 & 0 \end{bmatrix}. Find an elementary matrix E such that EA ...
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.
