Web9 okt. 2024 · Fact: For the invertible upper triangular matrix T 1, we need O ( n 2) operations to find its inverse. Finding x is equivalent to solving the following equation: ( T 1 − 1 + T 2) x = T 1 − 1 b. Using the fact above, computing the upper-triangular ( T 1 − 1 + T 2) needs O ( n 2) operations. WebUse Gauss-Jordan elimination on augmented matrices to solve a linear system and calculate the matrix inverse. These techniques are mainly of academic interest, since there are more efficient and numerically stable ways to calculate these values. Create a 3-by-3 magic square matrix. Add an additional column to the end of the matrix.
