... A square matrix A is called an upper triangular matrix, if all entries below the main diagonal are zero, i.e. for i > j : aij = 0. A square matrix A is called a lower triangular matrix, if all entries above the main diagonal are zero, i.e. for i < j : aij = 0. Theorem 8 (a) The transpose of a lower ...

... Additional Notes 1. Let u, v be vectors in Rn . Note the difference between u · v and uT v even though they evaluate to the same ’value’. 2. Matrix addition is defined on matrices of the same size. 3. Matrix multiplication is defined when the number of columns of the first matrix is the same as the ...
