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> Stan Devitt > -----Original Message----- > From: Russell Steven Shawn O'Connor > [SMTP:roconnor@wronski.math.uwaterloo.ca] > Sent: Friday, March 13, 1998 5:01 PM > To: www-math@w3.org > Cc: ion@math.ams.org > Subject: Default rendering for transpose > > > In section 4.4.10.5 the suggested rendering of transpose is > A<SUP>-1</SUP>.
