Web2 days ago · d. When we performed Gaussian elimination, our first goal was to perform row operations that brought the matrix into a triangular form. For our matrix A, find the row operations needed to find a row equivalent matrix U in triangular form. By expressing these row operations in terms of matrix multiplication, find a matrix L such that L A = U.
