负定矩阵和半负定矩阵的定义类似。非半正定和非半负定(not positive semi-definite and not negative semi-definite)的矩阵有时称为不定(indefinite)矩阵。 等效条件 从上述定义可知,矩阵是正定的当且仅当它是正定二次型( positive-definite quadratic form)或 Hermitian 型矩阵。换句话说,矩阵是正定的当且仅当它...
Positive semi-definite matrices are positive definite if and only if they are nonsingular.正半定矩阵是正定的，当且仅当它们是非奇异矩阵。
