Talk:Singular value decomposition

Why is there large font red text in the description?

The page description renders many words in large and bold font with bright red color. Why?

Failed to parse (syntax error): {\displaystyle X^{−1}AX}

Failed to parse (syntax error): {\displaystyle λx}

Failed to parse (syntax error): {\displaystyle A=UΣV^T}

Failed to parse (syntax error): {\displaystyle U,Σ,V}

Corrected the errors with the help of the wiki page "Help:Displaying a formula"

Corrected the errors messages, not sure about the first one ( ${\displaystyle X^{-1}AX}$ ) perhaps the A needs to be ${\displaystyle \land }$ (and). My first try at a math formula. --Frisian (talk) 00:53, 22 December 2024 (UTC)

I added some spaces which seemed to help, not that I know what I'm doing. Look ok to you? --Petelomax (talk) 09:21, 28 December 2024 (UTC)

Your right some spacing makes it more readable. Did not see any difference, the parser seems to ignore spaces. Looked it up, if you want a space in the formula you need to add a ~ or place a backslash (\) in front of the space.

      "U ,  \Sigma ,  V"  outputs  ${\displaystyle U,\Sigma ,V}$  
      "U ,\ \Sigma ,\ V"  outputs  ${\displaystyle U,\ \Sigma ,\ V}$  
      "U , ~\Sigma , ~V"  outputs  ${\displaystyle U,~\Sigma ,~V}$
