... Hence, solve the system of equations: –10x + 4y + 9z = 10, 15x – 4y – 14z = 20, –5x + y + 6z = –30. (ii) Express matrix A in part(i) above as the sum of a symmetric and a skew-symmetric matrix. Hint: if A is a square matrix, then A + AT is symmetric, while A – AT is skew-symmetric. (b) Find the ra ...

... (If we add one more condition, we will have the definition reduced row-echelon form.) 4. Every column with a leading 1 has a zero everywhere else in that column. Example 2. Which of the following matrices are in reduced rowechelon form? If it is not in reduced row-echelon form, state whether it is i ...
