Question

Using the matrices compute the following. $tr(5E^T - D) = $ $\begin{bmatrix} 0 & -4 & 0 \\ 0 & 0 & -4 \\ 0 & 0 & 4 \end{bmatrix}$, $E = \begin{bmatrix} 0 & 0 & 0 \\ 0 & 0 & 3 \\ 1 & -2 & -4 \end{bmatrix}$

          Using the matrices
compute the following.
$tr(5E^T - D) = $
$\begin{bmatrix} 0 & -4 & 0 \\ 0 & 0 & -4 \\ 0 & 0 & 4 \end{bmatrix}$, $E = \begin{bmatrix} 0 & 0 & 0 \\ 0 & 0 & 3 \\ 1 & -2 & -4 \end{bmatrix}$

Using the matrices
compute the following.
tr(5E^T - D) =
< b m a t r i x >, E =
< b m a t r i x >

Step 1

Without knowing the specific matrices, we cannot compute the trace directly. However, we can still explain the process. The trace of a matrix is the sum of its diagonal elements. So, to compute tr(SET ∪ D), we need to find the union of the two matrices SET and D, Show more…
