Condition number properties Assuming $A$ is invertible, I know if $A^{-1} = A^T$, then $cond(A)=1$. Is it true the other way around, as in If $cond(A)=1$, $A^{-1}=A^T$. Also, does $cond(A^{-1})$ always equal $con...

.$$ Then you can see that the condition number of $A$ is in fact $$cond(A)=\frac{|\lambda_1|}{|\lambda_n|}.$$ Next, you are going to use the fact that Finally, you can obtain the relation immediately: $$cond(A)=cond(A^{-1}).$$ Now if $cond(A)=1$, this means all eigenvalues of $A^TA$ equals $1$ because

Assuming you're using the spectral norm, the condition number of $A$ is $1$. But there is no matrix with condition number less than $1$, because $$1 = \|I\| = \|M M^{-1}\| \le \|M \| \|M^{-1}\|$$ for all invertible matrices $M$.

Singularity of a matix If $A$ is any $n\times n$ non-singular matrix, then $\mathrm{cond}(A) = \mathrm{cond}(A^{-1})$? True or False? I'm not sure how to answer this question.

Generally, we define $\mathrm{cond}(A)$ as $$\mathrm{cond}(A):=\vert\vert A\vert\vert\cdot \vert\vert A^{-1}\vert\vert.$$ So we do have $$\mathrm{cond }(A)=\vert\vert A\vert\vert\cdot \vert\vert A^{-1}\vert\vert=\vert\vert A^{—1}\vert\vert\cdot \vert\vert A\vert\vert=\mathrm{cond}(A^{-1})

We give an example in which $\operatorname{cond}(M)>\operatorname{cond}(Q)$ and an example in which $\operatorname{cond}(M)<\operatorname{cond}(Q)$, showing }(M)$, and for $a=0.1$ we get $\operatorname{cond}(Q)=10>\operatorname{cond}(M)$.

You've estimated a proportion of $\hat{p}=0.833564$ from $n=1000000$ trials. You can for example construct a $95\%$ confidence interval: $$[\hat{p}-1.96\sqrt{\frac{\hat{p}(1-\hat{p})}{n}},\hat{p}+1.96\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}]=[0.8329,0.8343]$$ So with $95\%$ confidence you can say that yo...

Application scenarios of sync.cond in Go (including examples and ...

The article provides an explanation of the concept, its definition, and its methods. It also presents an example of using sync.Cond in a scenario where multiple goroutines wait for a single goroutine to notify them. The article also compares sync.Cond with other synchronization concepts in Go, such as channels and sync.WaitGroup. blog.allwens.work

3.12 Conditionals: if, cond, and, and or - Racket

or. Conditionals in The Racket Guide introduces conditionals. syntax. ( if test-expr then-expr else-expr) Evaluates test-expr. If it produces any value other than #f, then then-expr is evaluated, and its results are the result for the if form. Otherwise, else-expr is evaluated, and its results are the result for the if form.

Since $A$ is orthogonal, $A^{-1}= A^T$ given $|| x||_1≤\sqrt n$ $Cond(A)= ||A||_1 * ||A^{-1}||_1 = ||A||_1 *||A^T||_1 ≤ \sqrt n * \sqrt n = n$
