Question Number 11218 by FilupS last updated on 17/Mar/17

at tinkutara there are major bugs with combining brackets. e.g. typing: ∣A⟩=(∣B^∗ ⟩)^T writing ∣⟩(∣A)^∗ then changing it to ∣⟩(∣A)^∗ ⟩ causes odd size glitches. furthermore, while typing my previous post, a huge glitch occured where tapping the screen (moving the cursor?) caused the text to get really really big

to see the last glitch, type: ⟨A∣=∣(A⟩)^T and then randomly add and delete, or delete and retype the ⟨⟩ ()^T and ∣ symbols

$$\mathrm{to}\:\mathrm{see}\:\mathrm{the}\:\mathrm{last}\:\mathrm{glitch},\:\mathrm{type}: \\ $$$$\langle{A}\mid=\mid\left({A}\rangle\right)^{\mathrm{T}} \: \\ $$$$\mathrm{and}\:\mathrm{then}\:\mathrm{randomly}\:\mathrm{add}\:\mathrm{and}\:\mathrm{delete}, \\ $$$$\mathrm{or}\:\mathrm{delete}\:\mathrm{and}\:\mathrm{retype}\:\mathrm{the}\:\langle\rangle\:\left(\right)^{\mathrm{T}} \:\mathrm{and}\:\mid\:\mathrm{symbols} \\ $$$$ \\ $$

Thanks. Although I like how brakets resize e.g. (((x^2 −1)/2))(x+1) I wish to write using “bra−ket”notation aka Dirac notation, but the rescalling poses a problem. e.g. ⟨A∣B⟩ this is good (⟨A∣)^n ∣B⟩ this is glitchy (try writing this)

Thanks for reporting the problem. We will test and fix the issue.

∣A⟩= ((A_1 ),(A_2 ),(⋮),(A_n ) ) here is an example of a broken ∣A⟩

$$\mid{A}\rangle=\begin{pmatrix}{{A}_{\mathrm{1}} }\\{{A}_{\mathrm{2}} }\\{\vdots}\\{{A}_{{n}} }\end{pmatrix}\:\:\:\:\mathrm{here}\:\mathrm{is}\:\mathrm{an}\:\mathrm{example}\:\mathrm{of}\:\mathrm{a}\:\mathrm{broken}\:\mid{A}\rangle \\ $$

may I suggest a version of ∣ ∙ ⟩, ⟨ ∙ ∣, ⟨ ∙ ∣ ∙ ⟩, ⟨ ∙ ∣ ∙ ∣ ∙ ⟩, etc, in the function menu? or, maybe provide a version of brackets that don′t have a ′scalling′. I personally like the 2nd option

We get the problem, bracket resize in pairs like [ x^2 ,1). We will address the problem or at least provide a manual override to size up or down a particular char

$$\mathrm{We}\:\mathrm{get}\:\mathrm{the}\:\mathrm{problem},\:\mathrm{bracket}\:\mathrm{resize} \\ $$$$\mathrm{in}\:\mathrm{pairs}\:\mathrm{like}\:\left[\:{x}^{\mathrm{2}} ,\mathrm{1}\right). \\ $$$$\mathrm{We}\:\mathrm{will}\:\mathrm{address}\:\mathrm{the}\:\mathrm{problem}\:\mathrm{or}\:\mathrm{at}\:\mathrm{least} \\ $$$$\mathrm{provide}\:\mathrm{a}\:\mathrm{manual}\:\mathrm{override}\:\mathrm{to}\:\mathrm{size} \\ $$$$\mathrm{up}\:\mathrm{or}\:\mathrm{down}\:\mathrm{a}\:\mathrm{particular}\:\mathrm{char} \\ $$
