How it works
The determinant is computed from the square matrix values. A non-zero determinant means the matrix is invertible.
Examples
- 2×2: determinant = ad − bc
- 3×3 and 4×4: computed with row-reduction based elimination
FAQ
- What is a determinant?
A determinant is a scalar value associated with a square matrix. It helps determine whether the matrix is invertible and describes certain geometric properties.
- Can I use any matrix size?
This tool supports square matrices from 2×2 to 4×4.
- What does determinant 0 mean?
A determinant of 0 means the matrix is singular and does not have an inverse.
- Are calculations stored?
