WebUsing matrix multiplication, we may define a system of equations with the same number of equations as variables as AX = B A X = B. To solve a system of linear equations using an inverse matrix, let A A be the coefficient matrix, let X X be the variable matrix, and let B B be the constant matrix. Thus, we want to solve a system AX =B A X = B. WebJan 31, 2024 · And even for a matrix as small as 1Kx1K, the LU is way faster. The greater speed of the sparse LU may make it fast enough that you won't even bother with an update at all. And for much of what you may do that needs the matrix inverse, you can often use an LU factorization just as easily.
