WebMath Advanced Math Let B be a 4x4 matrix to which we apply the following operations: 1. double column 1, 2. halve row 3, 3. add row 3 to row 1, 4. interchange columns 1 and 4, 5. subtract row 2 from each of the other rows, 6. replace column 4 by column 3, 7. delete column 1 (so that the column dimension is reduced by 1). WebWe can subtract 3 times row 1 of matrix A from row 2 of A by calculating the matrix product: ⎡ ⎤⎡ ⎤ ⎡ ⎤ ... which subtracts 3 times row 1 from row 2. To “undo” this operation we must add 3 times row 1 to row 2 using the inverse matrix: ⎡ ⎤ 1 0 0 E−1 = ⎣ 3 1 0 ⎦. 21 http://www.ams.stonybrook.edu/~jpetrill/210/hw/AMS210_HW5_SOL.pdf chubbs subs
