= Converting Latex Documents to Sage Worksheets = == Introduction == Latex documents can be translated to jsMath, the tool used to render mathematics in the Sage notebook. This project is about automating the conversion process so that authors can easily use a single command to convert a book-length Latex document to a collection of Sage worksheets. These could have embedded Sage input cells, possibly containing interacts, and the cross-referencing features of Latex would be preserved in the collection of Sage worksheets.<

Some tickets below that are available for review can be seen building and passing tests at the [[http://sage.math.washington.edu:21100/ticket/?author=rbeezer|Sage PatchBot]]. Failures can be due to improper listing of necessary prerequisites, or builds not caught up with latest alpha version, so do not necessarily mean a ticket is not ready for review. || Ticket || Description || Status || Acknowledgements || || [[http://trac.sagemath.org/sage_trac/ticket/8071 | 8071]] || trivial matrix kernels over non-fields || 4.4.alpha0 || Martin Albrecht || || [[http://trac.sagemath.org/sage_trac/ticket/10362|10362]] || vector constructor documentation || 4.6.1.alpha3 || Andrey Novoseltsev || || [[http://trac.sagemath.org/sage_trac/ticket/10422|10422]] || documentation fix on new_matrix constructor || 4.6.1.alpha3 || Benjamin Jones || || [[http://trac.sagemath.org/sage_trac/ticket/10189|10189]] || additions to all-ones matrix constructor || 4.6.2.alpha0 || Karl-Dieter Crisman, Robert Miller|| || [[http://trac.sagemath.org/sage_trac/ticket/10364|10364]] || zero_vector constructor, vector constructor error-checking || 4.6.2.alpha0 || Andrey Novoseltsev || || [[http://trac.sagemath.org/sage_trac/ticket/10424|10424]] || matrix augment accepts a vector || 4.6.2.alpha0 || Joris Vankerschaver, Robert Bradshaw || || [[http://trac.sagemath.org/sage_trac/ticket/10625|10625]] || generic Smith form fails on integer matrices || 4.6.2.alpha2 || Author: David Loeffler || || [[http://trac.sagemath.org/sage_trac/ticket/4492 | 4492]] || block matrix constructor || 4.6.2.alpha3 || Author: Willem Jan Palenstijn || || [[http://trac.sagemath.org/sage_trac/ticket/8948 | 8948]] || latex printing for vectors || 4.6.2.alpha3 || Author: Jason Grout || || [[http://trac.sagemath.org/sage_trac/ticket/10454|10454]] || add .is_singular() || 4.6.2.alpha3 || Robert Bradshaw || || [[http://trac.sagemath.org/sage_trac/ticket/10471|10471]] || conjugate-transpose of a matrix || 4.6.2.alpha3 || Robert Bradshaw || || [[http://trac.sagemath.org/sage_trac/ticket/10500|10500]] || documentation: matrix row/column linear combinations || 4.6.2.alpha3 || Alyson Deines || || [[http://trac.sagemath.org/sage_trac/ticket/10535|10535]] || column-oriented matrix constructor || 4.6.2.alpha3 || Dan Drake || || [[http://trac.sagemath.org/sage_trac/ticket/10537|10537]] || dictionary input to vector constructor || 4.6.2.alpha3 || Dima Pasechnik || || [[http://trac.sagemath.org/sage_trac/ticket/10626|10626]] || route sparse integer matrices to specialized Smith form || 4.6.2.alpha3 || David Loeffler || || [[http://trac.sagemath.org/sage_trac/ticket/10627|10627]] || matrix pretty-printing || 4.6.2.alpha3 || Author: Ivan Andrus || || [[http://trac.sagemath.org/sage_trac/ticket/10028|10028]] || improved error messages for non-invertible matrices || 4.6.2.alpha4 || Author: Andre Apitzsch || || [[http://trac.sagemath.org/sage_trac/ticket/10541|10541]] || row and column matrix from vector, deprecate transpose || 4.6.2.alpha4 || Volker Braun, Marco Streng || || [[http://trac.sagemath.org/sage_trac/ticket/10543|10543]] || echelon form over QQ is mutable || 4.6.2.alpha4 || Tom Coates || || [[http://trac.sagemath.org/sage_trac/ticket/10604|10604]] || diagonal matrix constructor rewrite || 4.6.2.alpha4 || Joint with: Dan Drake || || [[http://trac.sagemath.org/sage_trac/ticket/9796 | 9796]] || diagonal elements of a matrix || 4.6.2.rc0 || Tom Coates || || [[http://trac.sagemath.org/sage_trac/ticket/10714|10714]] || rows/columns of sparse matrices with zero rows/columns || 4.6.2.rc0 || Jason Grout || || [[http://trac.sagemath.org/sage_trac/ticket/10568|10568]] || speed-up scalar multiples of sparse matrices || 4.7.alpha1 || Author: Maarten Derickx || || [[http://trac.sagemath.org/sage_trac/ticket/10426|10426]] || matrix row and column swapping, returns new matrix || 4.7.alpha2 || Alain Filbois || || [[http://trac.sagemath.org/sage_trac/ticket/10763|10763]] || matrix multiplication speedup || 4.7.alpha2 || Author: Simon King || || [[http://trac.sagemath.org/sage_trac/ticket/10477|10477]] || random vector constructor || 4.7.alpha3 || Felix Lawrence || || [[http://trac.sagemath.org/sage_trac/ticket/10536|10536]] || vector conjugation || 4.7.alpha3 || Felix Lawrence || || [[http://trac.sagemath.org/sage_trac/ticket/10545|10545]] || outer product of vectors || 4.7.alpha3 || Felix Lawrence, John Palmieri || || [[http://trac.sagemath.org/sage_trac/ticket/10595|10595]] || vector constructor fails with empty list || 4.7.alpha3 || Joint: J.

> Anybody want to try for the round-trip, Latex -> SWS -> Latex? == jsMath Safe Boxes Edit == For Sage versions prior to 4.3.3.alpha0 (sagenb prior to 0.7.5) it is necessary to slightly tweak the jsMath configuration in Sage. It is a one-character edit. You can still view the sections, but "reasons" given in math displays (generally in proofs) won't render right and you will see lots of "@a()" stuff. This was fixed in [[http://trac.sagemath.org/sage_trac/ticket/8202 | Trac 8202]] for Sage 4.3.3. Check your version of Sage with {{{sage --version}}}. The file to edit is {{{ SAGE_ROOT/local/lib/python/site-packages/sagenb-0.6-py2.6.egg/sagenb/data/sage/js/jsMath.js }}} where you might have to adjust the numbering on the {{{sagenb}}} package. Then at line 97 (or thereabouts) make the following change {{{ jsMath.safeHBoxes=1 --> jsMath.safeHBoxes=0 }}}
