How to edit matrix

Is there a way to remove the right vertical line in this matrix:
enter image description here



documentclass{article}

 usepackage{amsmath} 

begin{document}

   $    begin{vmatrix} alpha & -& beta =180\ alpha & +&beta =68

end{vmatrix}$  

end{document}

You maybe want to use systeme, rather than a matrix for that, which makes for even easier input:



documentclass{article}

usepackage{amsmath}

usepackage{systeme}



begin{document}



[

systeme[alphabeta]{

  alpha-beta=180,

  alpha+beta=68

}

]

[

sysdelim|.

systeme[alphabeta]{

  alpha-beta=180,

  alpha+beta=68

}

]

[

syssubstitute{{a}{alpha}{b}{beta}}

systeme[alphabeta]{

  3alpha -  beta = 180,

   alpha + 2beta = 68

}

]



end{document}


The traditional grouping is done with a brace, but you can also use a vertical bar as shown. If you want that all your systems have a vertical bar, type the sysdelim|. command in the preamble.



enter image description here



Latin letters need not be declared as variables in the optional argument to systeme.

It does work with matrix:

    I would do 



    documentclass{article} 
    
usepackage{amsmath} 
    
begin{document} 
    
$ left| begin{array}{@{}*{4}{c@{,}}l} 
    
alpha & -& beta &=&180\ 
    
alpha & +&beta &=&68 
    
end{array}right.$ 
    
end{document}


    This is more effort, but avoids potential headaches like here, here and here.

                  I would do 



                  documentclass{article} 
                  
usepackage{amsmath}

$ left| begin{array}{@{}*{4}{c@{,}}l} 
                  
alpha & -& beta &=&180\ 
                  
alpha & +&beta &=&68

                      How to label and detect the document text images

                      Image
                      1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...

                      Tabula Rosettana

                      Image
                      Tabula multilinguis Rosettana in Museo Britannico ostenditur. Tabula Rosettana, [1] etiam titulo OGIS 90 agnita, est stela decreto de rebus sacris in Aegypto anno 196 a.C.n. lato inscripta. Tabula iuxta Rosettam Aegypti, urbem in delta Nili et ad oram maris Mediterranei iacentem, anno 1799 a milite Francico reperta est. Inventio stelae, linguis duabus scripturisque tribus inscriptae, eruditis Instituti Aegypti statim nuntiata est; ibi enim iussu imperatoris Napoleonis eruditi omnium scientiarum (sub aegide Commissionis Scientiarum et Artium) properaverant cum expeditione Francica. Qua a Britannis mox debellata, tabula Rosettana Londinium missa hodie apud Museum Britannicum iacet. Textus Graecus cito lectus interpretationi textuum Aegyptiorum (in formis hieroglyphica et demotica expressorum) gradatim adiuvit. Denique textum plene interpretatus est Ioannes Franciscus Champollion. Ab opere eruditorum cumulativo coepit hodiernus scripturae hieroglyphicae linguaeque Aegyptiae a...
