A walkthrough, end to end.
- 1
Enter matrix A (and B for binary operations) using rows separated by newlines and entries by spaces or commas.
- 2
Pick the operation: A+B, A−B, A×B, transpose Aᵀ, or det(A).
- 3
Results appear instantly — dimensions are validated automatically.
Matrix operations
Add/subtract: same dimensions, entry-wise. Multiply: A is m×n and B is n×p; result is m×p. Determinant: square matrices, computed via Laplace expansion.
