WebThe matrix determinant is a number derived from the values in array. For a three-row, three-column array, A1:C3, the determinant is defined as: MDETERM (A1:C3) equals A1* (B2*C3-B3*C2) + A2* (B3*C1-B1*C3) + A3* (B1*C2-B2*C1) Matrix determinants are generally used for solving systems of mathematical equations that involve several variables.

In mathematics, the determinant is a scalar value that is a function of the entries of a square matrix. It characterizes some properties of the matrix and the linear map represented by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible and the linear map represented by the matrix is an isomorphism. The determinant of a product of matrices is the product of their determinants (the preceding property is a corollary of this one). The determinan… WebDeterminant of a Matrix. By Catalin David.
