Matrices

When to Use

Use this skill when working on matrices problems in linear algebra.

Decision Tree

  • Identify Matrix Type
  • Square, symmetric, orthogonal, diagonal?
  • Check properties with sympy_compute.py matrix_type
  • Basic Operations
  • Multiplication: sympy_compute.py matmul "A" "B"
  • Inverse: sympy_compute.py inverse "A"
  • Transpose: sympy_compute.py transpose "A"
  • Solve Linear Systems
  • Ax = b: sympy_compute.py linsolve "A" "b"
  • Check consistency with z3_solve.py sat
  • 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]"

How to use it

Copy the folder

Take vibeeval/matrices from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
