The following MCE points out that DeclareMathOperator, if its second argument (name text) contains periods, adds spaces after those periods:



documentclassarticle
usepackageamsmath
%
DeclareMathOperatorlimonel.i.m.
newcommandlimtwomathopmathrml.i.m.

beginalign*
 A_t & =limone A_n,t \
 A_t & =limtwo A_n,t \
 A_t & =textl.i.m. A_n,t
endalign*
enddocument


enter image description here



Do you know why and how to get rid of these spaces?

  • DeclareMathOperatorlimonel.i.m. Note that while the l.i.m. will still line up with your text case, there will be a gap following the last ., because l.i.m. is now an operator, whereas textl.i.m. is a math atom.

  • Using . ? Untested, it just makes the dot an ord. Which math operator is that? Never seen one with punctuation in it before

  • @daleif . works nicely indeed. Concerning the operator, some authors use it for denoting the convergence in the mean square sense. I agree it is quite strange :)

Compare with



$lmathpunct.imathpunct.m$


Indeed, your limone gives qopname newmcodes@ ol.i.m. and newmcodes assigns mathpunct category to the dot (which will be taken in letters font, not operators...). Another strangeness of newmcodes@.



newmcodes@ ->mathcode `'39mathcode `*42mathcode `."613Aifnum mathcode 
`-=45 else mathchardef std@minus mathcode `-relax fi mathcode `-45ma
thcode `/47mathcode `:"603Arelax


You will have same mathpunct spacing with :. enter image description here



What to do? You can always define your own newmcodes@ to replace above definition.

    I guess that when the code for qopname was being developed by Spivak and the AMS (it went essentially unchanged into amsmath.sty from amstex.tex) the use cases dictated that the period had to be considered as punctuation in an operator name.

Displaying single band from multi-band raster using QGIS

Clash Royale CLAN TAG #URR8PPP 1 How can I extract a single band from multi-band raster in QGIS? I have an remote sensed image which has 6 bands (including NDVI band), I want to display each band separately, but have no idea how to do. I have seen some questions similar here but none worked for me. The original image (has 6 bands) is: I want to display the band 6 which should be like this: But I tried gdal_translate, and couldn't get the correct result.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
