How this service works
Matrix determinant, inverse, transpose, rank, trace, product with a second matrix, and eigenvalues of 2x2 and 3x3 matrices.
Output
Returns a JSON object with the requested matrix operation result: a scalar for determinant/trace/rank, a 2D array for inverse/transpose/product, an array of values for eigenvalues, and optionally a condition number (infinity norm). Also includes summary and reasons fields explaining the result and any warnings (e.g. singular matrix).
Example use cases
Eigenvalue analysis for physics simulation
“I have a 3x3 matrix [[4,1,0],[1,3,2],[0,2,5]] — can you find its eigenvalues and tell me if it's invertible by computing the determinant?”
Matrix multiplication for transformation pipeline
“Multiply these two 3x3 matrices together for me: first is 1,2,3;4,5,6;7,8,9 and second is 9,8,7;6,5,4;3,2,1.”
Check if system of equations has unique solution
“I need to know if this 2x2 matrix [[3,7],[1,5]] is full rank and invertible — can you give me its rank, determinant, and inverse?”
Technical details
Endpoint
GEThttps://math-geometry.x402tookit.com/matrix-ops?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, precise linear algebra computations on small (2x2 or 3x3) matrices — particularly for determinants, inverses, eigenvalues, or matrix products in agentic math workflows. Prefer it over general-purpose CAS tools when you want a low-cost, single-purpose REST call that returns structured JSON. Not suitable for larger matrices or symbolic/parametric computation.
Side effects
- Matrix is singular — inverse cannot be computed, endpoint returns null for inverse field
- Matrix dimensions exceed 3x3 — only 2x2 and 3x3 supported
- Malformed matrix string (wrong delimiter, non-numeric values) causes parse error
- Missing required query parameter 'op' or 'matrix'
- 'other' matrix not provided when op is 'multiply'
- Non-square matrix passed to an operation requiring square input (e.g. determinant, inverse, eigenvalues)
