This inverse matrix calculator help you to find the inverse matrix. A -1 × A = I. Definition method. However, any of these three methods will produce the same result. In this section we see how Gauss-Jordan Elimination works using examples. If matrix A can be eigendecomposed, and if none of its eigenvalues are zero, then A is invertible and its inverse is given by − = − −, where is the square (N×N) matrix whose i-th column is the eigenvector of , and is the diagonal matrix whose diagonal elements are the corresponding eigenvalues, that is, =.If is symmetric, is guaranteed to be an orthogonal matrix, therefore − =. To solve a system of linear equations using inverse matrix method you need to do the following steps. Our online calculator supports two different methods of matrix inverse calculation: by means of Gauss-Jordan method and by means of algebraic adjuncts compositions to the initial matrix.
