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. WebNote: (a) The matrix is just an arrangement of certain quantities. (b) The elements of a matrix may be real or complex numbers. If all the elements of a matrix are real, then the matrix is called a real matrix. (c) An m x n matrix has m.n elements. Illustration 1: Construct a 3×4 matrix A = [a ij ], whose elements are given by a ij = 2i + 3j.
