How this service works
Matrix calculator for up to 8x8 - determinant, inverse, rank, trace, transpose and the solution of the linear system Ax = b with a square matrix
Output
A JSON object containing: number of rows and columns, whether the matrix is square, its rank, trace (null for non-square), determinant (null for non-square), whether it is invertible, the inverse matrix (null if not invertible), the transposed matrix, and the solution vector x for Ax=b if a vector b was provided.
Example use cases
Solve system of linear equations
“I have a system of 3 equations with 3 unknowns. The coefficient matrix is [[2,1,-1],[−3,−1,2],[−2,1,2]] and the right-hand side vector b is [8,−11,−3]. Can you solve for x?”
Check matrix invertibility and get inverse
“Is the matrix [[4,7],[2,6]] invertible? If so, what's its inverse and what's the determinant?”
Analyze 4x4 matrix properties
“I need the rank, trace, and transpose of this 4x4 matrix: [[1,2,3,4],[5,6,7,8],[9,10,11,12],[13,14,15,16]].”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/math/matrix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick, accurate linear algebra computations on matrices up to 8x8, especially when you need multiple properties (determinant, inverse, rank, trace, transpose) in a single call or need to solve a linear system Ax=b. It's ideal for educational tools, engineering calculations, or any workflow requiring symbolic or numerical matrix analysis without standing up a local math library.
Side effects
- Matrix larger than 8x8 rejected
- Malformed JSON array in matrix parameter causes error
- Non-numeric values in matrix cause computation failure
- Solving Ax=b with a singular (non-invertible) matrix returns null solution
- Missing required matrix parameter returns error
- Providing vector b with a non-square matrix may return null solution
