Inverse matrix can be calculated using different methods. Learn what is inverse matrix, how to find the inverse matrix for 2x2 and 3x3 matrices along with the steps and solved examples here at BYJU'S.
The inverse of the 3x3 matrix can be determined by calculating the determinant and matrix of cofactors and then dividing each term by determinant. Learn more at BYJU'S.
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.
The inverse is the transpose of the matrix where each element is thedeterminantof its minor (with a sign calculation) divided by the determinant of the whole. To calculate this we can follow these steps: Calculate the minor for every matrix element. Form the cofactor matrix from the minors w...
FINDING AN INVERSE MATRIX To obtain A^(-1)n x nmatrix A for which A^(-1) exists, follow these steps. 1. Form the augmented matrix [A/I], where I is then x nidentity matrix. 2. Perform row transformations on [A|I] to get a matrix of the form [I|B]. ...

For a square matrix {eq}A {/eq}, the multiplicative inverse is given by, {eq}AA^{-1}=I=A^{-1}A {/eq}. How do you find the multiplicative inverse of a 2x2 matrix? The multiplicative inverse of a 2x2 matrix is obtained only if the matrix is invertible. The inverse of such a...
and use Gaussian elimination on the 6-element rows of the matrix to transform it into something of the form: (100⋮x1x2x3010⋮y1y2y3001⋮z1z2z3)⎝⎛100010001⋮⋮⋮x1y1z1x2y2z2x3y3z3 where the xx's, yy's, and zz's are obtained along the way from the transformatio...
