tiny etc. in mathmode

I read everywhere that tiny, etc. does not work in mathmode. When I use it in my code, I also get a warning Command tiny invalid in math mode. But in the output it nevertheless works. At least in some places.



I suppose on other machines this will not work, so I would like to not use these commands in math mode. But, all other commands to make small fonts in mathemode do not work as well as tiny does. E.g. in the following MWE



documentclass{scrbook}
begin{document}
$M_{begin{array}{c}2\2end{array}2A}$
$M_{tinybegin{array}{c}2\2end{array}2A}$
$M_{scriptsizebegin{array}{c}2\2end{array}2A}$
$M_{scriptstylebegin{array}{c}2\2end{array}2A}$
$M_{scriptscriptstylebegin{array}{c}2\2end{array}2A}$
end{document}


enter image description here



The output I want, is the second. I have a subscript consisting of an array, and this array shall have small numbers.
But tiny is the only command which accomplishes that.



Now to my questions:




  1. How do I make small subscripts as in the second example without the use of tiny.

  2. Why does tiny work for the array-subscript, but not for the standard subscript.

  3. Why does scriptscriptstyle work for the standard subscript, but not for the array-subscript.




This question is not a duplicate to
Size commands do not work in mathmode
since I am also asking why tiny works, although it is written everywhere that it is not working (and furthermore, @egreg said it is no duplicate).

Size commands do not work in math mode. However (some) size commands set up math so if you enter a new math expression from text while the size change is in force, you get math of a matching size. Internally array is an halign in which each cell is surrounded by $...$ so in fact using array is like using mbox{empty text $ matrix cell$} so the entries pick up the size change more or less by accident.



documentclass{scrbook}
usepackage{amsmath}
begin{document}
$M_{begin{smallmatrix}2\2end{smallmatrix}2A}$

You could define a tinymatrix environment modeled on smallmatrix:



documentclass{article}
usepackage{amsmath}

makeatletter
% from amsmath.sty, line 960:
newenvironment{tinymatrix}{null,vcenterbgroup
Let@restore@math@crdefault@tag
baselineskip4ex@ lineskip1.2ex@ lineskiplimitlineskip
ialignbgrouphfil$m@thscriptscriptstyle##$hfil&&thickspacehfil
$m@thscriptscriptstyle##$hfilcrcr
}{%
crcregroupegroup,%
}
makeatother

newcommand{di}[1]{begin{tinymatrix}#1end{tinymatrix}}

begin{document}

[
M_{di{2\2}2A}
]

end{document}

    A simple way to change the font size in math mode is to put the size-changing command inside a mbox, for example:



    documentclass[varwidth, preview]{standalone}
    usepackage[T1]{fontenc} % Or unicode-math
    usepackage[utf8]{inputenc} % The default since 2018.

    newcommandmscriptsize[1]{mbox{scriptsizeensuremath{#1}}}
    newcommandmtiny[1]{mbox{tinyensuremath{#1}}}

    begin{document}
    ( x mscriptsize{y} mtiny{omega} )
    end{document}


    x y ω



    You might want only the braces if you need a long expression to wrap.



    You can also use text from amsmath to insert arbitrary text-mode commands within math mode, such as text{tinyitshape x}.

              x y ω



              You might want only the braces if you need a long expression to wrap.



              You can also use text from amsmath to insert arbitrary text-mode commands within math mode, such as text{tinyitshape x}.

                A simple way to change the font size in math mode is to put the size-changing command inside a mbox, for example:



                documentclass[varwidth, preview]{standalone}
                usepackage[T1]{fontenc} % Or unicode-math
                usepackage[utf8]{inputenc} % The default since 2018.

                newcommandmscriptsize[1]{mbox{scriptsizeensuremath{#1}}}
                newcommandmtiny[1]{mbox{tinyensuremath{#1}}}

                begin{document}
                ( x mscriptsize{y} mtiny{omega} )
                end{document}


                x y ω



                You might want only the braces if you need a long expression to wrap.
