WebMar 24, 2024 · An n×n complex matrix A is called positive definite if R[x^*Ax]>0 (1) for all nonzero complex vectors x in C^n, where x^* denotes the conjugate transpose of the vector x. In the case of a real matrix A, equation (1) reduces to x^(T)Ax>0, (2) where x^(T) denotes the transpose. Positive definite matrices are of both theoretical and computational … WebTo evaluate the determinant of the given symmetric matrix, we can use the Laplace expansion method along the first row.

WebA matrix for which the transposed form is equal to the negative of the original matrix is called a skew-symmetric matrix. Any matrix can be expresses as a sum of a symmetric and a skew-symmetric matrix. For a square matrix A, A = (1/2)(A + A T) + (1/2)(A - A T). If the order of a skew-symmetric matrix is odd, then its determinant is equal to zero. WebApr 7, 2024 · The amount had been written off as bad debts earlier.
