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?

    No. Everything runs locally in your browser.
