**Solution to Coordinate Transformation Problem**

Given the ordered basis \( \mathcal{B} = \{ A_1, A_2, A_3, A_4 \} \):

- \( A_1 = \begin{bmatrix} -1 & -5 \\ 4 & -2 \end{bmatrix} \)
- \( A_2 = \begin{bmatrix} 0 & 1 \\ 9 & 5 \end{bmatrix} \)
- \( A_3 = \begin{bmatrix} -1 & 3 \\ 0 & -9 \end{bmatrix} \)
- \( A_4 = \begin{bmatrix} 6 & 4 \\ 8 & -8 \end{bmatrix} \)

Find \( [A]_{\mathcal{B}} \), the coordinates of \( A = \begin{bmatrix} -16 & -19 \\ -33 & 37 \end{bmatrix} \) with respect to \( \mathcal{B} \).

**Task Explanation:**
This problem requires finding the coordinates of matrix \( A \) in terms of the ordered basis \( \mathcal{B} \). The coordinates represent how to express matrix \( A \) as a linear combination of the given basis matrices \( A_1, A_2, A_3, A_4 \).

\[ [v]_{\mathcal{B}} = \begin{bmatrix} \text{Ex: 5} \\ \text{(empty)} \\ \text{(empty)} \\ \text{(empty)} \end{bmatrix} \]

**Instructions:**
1. Set up an equation expressing \( A \) as a linear combination of the basis matrices.
2. Solve for the coefficients that represent \( [A]_{\mathcal{B}} \).
