How to solve for inverse matrix
WebApr 9, 2024 · Inverse Matrix Formula The first step is to calculate the determinant of the 3 * 3 matrix and then find its cofactors, minors, and adjoint and then include the results in the below-given inverse matrix formula. A − 1 = 1 / A Adj(A) Inverse of 3 X 3 Matrix Example Let us solve the 3 X 3 matrix [a b c d e f g h i] Examine the given 3 X 3 matrix WebYour solution looks right. $\mathbf{x}$ is the vector of variables, i.e. $\mathbf{x}=(x,y)^\top$ in your case. The "dimensions" of $\mathbf{x}$ and $\mathbf{b}$ are necessary from the matrix equation. Note, that you have a $2\times 2$-matrix multiplied from the right by a column vector, necessarily of dimension $2\times 1$ for matrix multiplication to be well …
