# Don’t Invert the Matrix

A common issue with linear algebra textbooks is the depiction of $latex {\bf x}={\bf A}^{-1}{\bf b}$ as the solution to the linear system of equations $latex {\bf A}{\bf x}={\bf b}$. Find the inverse of the matrix $latex {\bf A}$, then multiply that inverse with the right-hand side vector, $latex {\bf b}$. Theoretically correct? Yes. Practical? … Continue reading Don’t Invert the Matrix
