3 матрица отдачи
матрица, отрицательно определенная — negative definite matrix
матрица, отрицательно полуопределенная — negative semidefinite matrix
матрица, положительно определенная — positive definite matrix
Обращением неравенств в условии z . Mz ≤ 0 получаем концепции положительно полуопределенной и положительно определенной матриц. — Reversing the inequalities in condition z . Mz ≤ 0, we get the concepts of positive semidefinite and positive definite matrices.
матрица, положительно полуопределенная — positive semidefinite matrix
