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"
- Multiplication:
-
Solve Linear Systems
- Ax = b:
sympy_compute.py linsolve "A" "b" - Check consistency with
z3_solve.py sat
- Ax = b:
-
Decompositions
- LU:
sympy_compute.py lu "A" - QR:
sympy_compute.py qr "A" - SVD:
sympy_compute.py svd "A"
- LU:
