WebThe determinant of a matrix is the scalar value determined for a given square matrix. A square matrix is a matrix in which number of rows and columns must be the same. Hence, It's not possible to find the determinant of a 2 × 3 matrix because it is not a square matrix. Suggest Corrections. 0. WebDeterminants. Determinants are the scalar quantities obtained by the sum of products of the elements of a square matrix and their cofactors according to a prescribed rule. They help to find the adjoint, inverse of a matrix. Further to solve the linear equations through the matrix inversion method we need to apply this concept.
