Let's solve the given problem using matrices.

### Problem Statement

Find the coordinates \( x_1, x_2, x_3 \) of the vector \( \mathbf{v} = (m, 0, 1) \) in the basis \( \{ \mathbf{u}_1, \mathbf{u}_2, \mathbf{u}_3 \} \), where:
\[
\mathbf{u}_1 = (1, 0, 0), \quad \mathbf{u}_2 = (1, 1, 0), \quad \mathbf{u}_3 = (0, -1, 1)
\]

This means we need to express \( \mathbf{v} \) as a linear combination of \( \mathbf{u}_1, \mathbf{u}_2, \mathbf{u}_3 \):
\[
\mathbf{v} = x_1 \mathbf{u}_1 + x_2 \mathbf{u}_2 + x_3 \mathbf{u}_3
\]

### Step-by-Step Solution

1. **Write the vector equation in terms of the basis vectors:**

\[
(m, 0, 1) = x_1 (1, 0, 0) + x_2 (1, 1, 0) + x_3 (0, -1, 1)
\]

2. **Expand the right-hand side:**

\[
(m, 0, 1) = (x_1, 0, 0) + (x_2, x_2, 0) + (0, -x_3, x_3)
\]

3. **Combine like terms:**

\[
(m, 0, 1) = (x_1 + x_2, x_2 - x_3, x_3)
\]

4. **Set up the system of equations by comparing components:**

\[
\begin{cases}
x_1 + x_2 = m \\
x_2 - x_3 = 0 \\
x_3 = 1
\end{cases}
\]

5. **Solve the system of equations:**

From the third equation, we get:
\[
x_3 = 1
\]

From the second equation, substitute \( x_3 = 1 \):
\[
x_2 - 1 = 0 \implies x_2 = 1
\]

From the first equation, substitute \( x_2 = 1 \):
\[
x_1 + 1 = m \implies x_1 = m - 1
\]

### Solution

The coordinates of \( \mathbf{v} \) in the given basis are:
\[
(x_1, x_2, x_3) = (m - 1, 1, 1)
\]
