In mathematics, the determinant is a scalar -valued function of the entries of a square matrix. The determinant of a matrix A is commonly denoted det (A), det A, or |A|. Its value characterizes some properties of the matrix and the linear map represented, on a given basis, by the matrix.

Determinant of a Matrix - Math is Fun

To work out the determinant of a 3×3 matrix: Multiply a by the determinant of the 2×2 matrix that is not in a 's row or column. As a formula (remember the vertical bars || mean "determinant of"): "The determinant of A equals a times the determinant of ... etc" The pattern continues for 4×4 matrices: As a formula:

Determinant -- from Wolfram MathWorld

Determinants are mathematical objects that are very useful in the analysis and solution of systems of linear equations. As shown by Cramer's rule, a nonhomogeneous system of linear equations has a unique solution iff the determinant of the system's matrix is nonzero (i.e., the matrix is nonsingular).

The determinant is a number associated with any square matrix; we’ll write it as det A or |A|. The determinant encodes a lot of information about the matrix; the matrix is invertible exactly when the determinant is non-zero.
