How to solve for inverse 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 … WebInversion works the same way for matrices. If you multiply a matrix (such as A) and its inverse (in this case, A −1), you get the identity matrix I, which is the matrix analog of the …
