所有这些都将在第五章,特别是第V.2节中讨论。 然而, \mathbb{Q},\mathbb{R},\mathbb{C} 更加特别一些,因子它们都是域(domain)。 定义1.11: 对于环元素 u\in R 左单位(left-unit):若 \exists\ v\in R: uv = 1 , 则称 u 为左单元。 右单位(right-unit):若 \exists\ v\in R: vu = 1...
Pay attention to the sign of the dot product and cos[u,v] when the angle between u and v changes from less than π/2 to greater than π/2. Note also that when u and v are unit vectors, i.e., ‖u‖=‖v‖=1, then u⋅v=cos[u,v]. Another insight can be gained when one...

Both matrices have unit diagonal and off-diagonal elements bounded in modulus by . So , yet So is ill conditioned for large . In fact, if we change the element of to then the matrix becomes singular! By contrast, is always very well conditioned. The determinant cannot distinguish between th...
Polynomial mapping\(\mathfrak p(S)\)is a compact notation for applying a polynomial or a function through a set, as it occurs to unit vector sets, meaning that $$\begin{aligned} \mathfrak p(S) = \{\mathfrak p(s) \mid s \in S\}. \end{aligned}$$ ...
(2) A is tridiagonal, A-1is a full matrix. (3) If L is lower triangular with 1’s on the diagonal, so is L-1 2.6 Elimination = Factorization: A=LU or A=LDU The factors are triangular matrices and the factorization comes from elimination. ...
Thus, for example, the six roots of $x^{6}=1$ are $\left(\cos\frac{\pi}{3},\sin\frac{\pi}{3}\right),\left(\cos\frac{2\pi}{3},\sin\frac{2\pi}{3}\right)\cdots\left(\cos\frac{5\pi}{3},\sin\frac{5\pi}{3}\right)\left(1,0\right)$ ...
