reassigned to bh (the component is called "Formula editor") I'll mark this one as a duplicate of issue 21484 although it faces import problems, the cause (and solution) is the same. Regarding the dagger: OpenSymbol contains a dagger, so you can create a new symbol-entry and use a real dagger instead of a plus sign. In case you don't know how to add user defined symbols see http://documentation.openoffice.org/user_faq/formula/012.html (the dagger is the rightmost symbol in the fourth row, counted from the top, U+2020) I think the solar-symbols you're looking for are included in opensymbol (U+2259 and following) "circled plus" -> oplus "circled minus" -> ominus "circled times" "circled division slash" -> odivide and so on... I'm not sure about this. If these aren't the symbols you need please file a sperate issue to have them added. Regarding the bra ket -thing I assume you want something like left langle a mline right none newline left none mline b right rangle newline left langle a mline b mline c right rangle newline left none mline a right rangle left langle b mline right none But again, to have a new notation introduced a sperate issue is absolutely necessary. The last point (TeX-style notation) please see issue 2864 *** This issue has been marked as a duplicate of 21484 *** closing duplicate. (the dagger is in the fourth row when you select the special-symbolset (and not greek) before launching the Edit-Symbol dialog) And you can of course define a new name for the "*", like for the dagger, a symbol created this way is not a binary operator so you could use A^%cconjugate (given that you name the symbol "cconjugate" You may also file an issue to have the character U+22B9 HERMITIAN CONJUGATE MATRIX added to Opensymbol (I assume that is the character you really want and the asterisk is just a workaround, but I have no clue about that :-) |
Hi: there are issues with how to code for the following mathematical/scientific notations in Math: Complex conjugation: the complex conjugate of "A" is A<sup>*</sup>. However, due to * being a binary operator, OOo requires that the kludgy "A^{{}*{}}" is used instead of the simple "A^*". These are used in mathematics and physics extensively. Dagger operator: Dagger operators are used in Quantum Mechanics. They are represented by a superscript dagger, similar to A<sup>+</sup>. However, + is also a binary operator, so kludgyness is required for even this workaround. Solar/Earth notation: the standard symbols denoting solar- or earth- masses or radii are a circle with a dot in the centre and a quartered circle. Both appear to be absent from the available symbols: lecturers using OOo have often used M_%THETA which looks almost good enough for the solar mass. These are used in astronomy. brakets: "bra A" looks like <A| . "ket B" looks like |B> . "bra A B ket C" looks like <A|B|C> . "ket A bra B" looks like |A><B| . These are vitally important in Quantum Mechanics (Dirac Notation). Current workarounds are: {} < A divides {} {} divides B > {} {} < A divides B divides C > {} {} divides A > {} < B divides {} which are excessively kludgy. A few apologies and questions: Sorry it's in Word processor; couldn't find Math category. Is there one? Sorry it's not one issue / one bug: much the same problem. Is there any reason why we don't use TeX format? It's widely known within the groups that will be using this sort of facility widely.
