On this page we number the matrix elements with two index numbers the first represents the column, the second the row. The index numbers start at 0 as follows: Other notation conventions are explainedon this page. Description The invese of a 3x3 matrix is: [M]-1= 1/det[M] * where: ...
There are several steps to finding the inverse of a 3x3 matrix. The first requirement, as with all matrices, is to compute the determinant and make sure that \(\det(A) \ne 0\). Then, we need to recall the generic adjoint formula \[ A^{-1} = \displaystyle \frac{1}{\det(A)} ...

Free online Inverse Matrix Calculator computes the inverse of a 2x2, 3x3 or higher-order square matrix. Also, eigenvalues, diagonalization, other properties of matrices.
This problem will discuss the operations that we perform to find the inverse of a (2×2) matrix and (3×3) matrix. It is fairly simple for a smaller matrix but a little tedious for the larger matrix. We perform operations either on the row or column to find the inverse of the ...
