RE: Default rendering for transpose

Thanks for the feedback.

Yes  indeed, A<SUP>-1</SUP>. is a typo.

For matrix inverse, make use one of one of

<apply><inverse/>
<ci type="matrix"> A </ci>
</apply>

or 

<apply><inverse/>
<matrix>
<matrixrow> <cn> 1 </cn> <cn> 2 </cn> </matrixrow>
<matrixrow> <cn> 3 </cn> <cn> 7 </cn> </matrixrow>
</matrix>
</apply>


Your suggestion regarding supporting columns as well
as rows is of interest, though note that even if no change 
were made, this could still be achieved by using

<declare definitionURL="..." type="function"><ci>mymatrix</ci></declare>
<declare definitionURL="..."
type="function"><ci>mymatrixrow</ci></declare>
<declare definitionURL="..."
type="function"><ci>mymatrixcol</ci></declare>

and

<matrix definitionURL="URL for a modified definition">
<apply><ci>matrixcol</ci> <cn> 1 </cn> <cn> 3 </cn> </apply>
<apply><ci>matrixcol</ci> <cn> 2 </cn> <cn> 7 </cn> </apply>
</matrix>

or 

<apply>
<ci>mymatrix</ci>
<apply><ci>matrixcol</ci> <cn> 1 </cn> <cn> 3 </cn> </apply>
<apply><ci>matrixcol</ci> <cn> 2 </cn> <cn> 7 </cn> </apply>
</apply>
