Web24 de mar. de 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 … Web2 de nov. de 2024 · A non-square matrix can have left and right inverse matrices. Left and right inverse matrices may not be the only ones.
