Matrices
When to Use
Use this skill when working on matrices problems in linear algebra.
Decision Tree
1. **Identify Matrix Type**
- Square, symmetric, orthogonal, diagonal?
- Check properties with `sympy_compute.py matrix_type`
2. **Basic Operations**
- Multiplication: `sympy_compute.py matmul "A" "B"`
- Inverse: `sympy_compute.py inverse "A"`
- Transpose: `sympy_compute.py transpose "A"`
3. **Solve Linear Systems**
- Ax = b: `sympy_compute.py linsolve "A" "b"`
- Check consistency with `z3_solve.py sat`
4. **Decompositions**
- LU: `sympy_compute.py lu "A"`
- QR: `sympy_compute.py qr "A"`
- SVD: `sympy_compute.py svd "A"`
Tool Commands
Sympy_Inverse
uv run python -m runtime.harness scripts/sympy_compute.py inverse "[[1,2],[3,4]]"
Sympy_Det
uv run python -m runtime.harness scripts/sympy_compute.py det "[[a,b],[c,d]]"
Sympy_Linsolve
uv run python -m runtime.harness scripts/sympy_compute.py linsolve "[[1,2],[3,4]]" "[5,6]"

Questions about matrices.
- Which coding agents can use matrices?
- matrices installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
