Output functions

These are the output functions for latexing partitions and tableaux.

AUTHORS:

  • Mike Hansen (?): initial version
  • Andrew Mathas (2013-02-14): Added support for displaying conventions and lines, and tableaux of skew partition, composition, and skew/composition/partition/tableaux tuple shape.
sage.combinat.output.tex_from_array(array, with_lines=True)

Return a latex string for a two dimensional array of partition, composition or skew composition shape

INPUT:

  • array – a list of list

  • with_lines – a boolean (default: True)

    Whether to draw a line to separate the entries in the array.

Empty rows are allowed; however, such rows should be given as [None] rather than [].

The array is drawn using either the English or French convention following Tableaux.global_options`().

EXAMPLES:

sage: from sage.combinat.output import tex_from_array
sage: print tex_from_array([[1,2,3],[4,5]])

sage.combinat.output.tex_from_array_tuple(a_tuple, with_lines=True)

Return a latex string for a tuple of two dimensional array of partition, composition or skew composition shape.

INPUT:

  • a_tuple – a tuple of lists of lists
  • with_lines – a boolean (default: True) Whether to draw lines to separate the entries in the components of a_tuple.

sage.combinat.output.tex_from_skew_array(array, with_lines=False, align='b')

This function creates latex code for a “skew composition” array. That is, for a two dimensional array in which each row can begin with an arbitrary number None‘s and the remaining entries could, in principe, be anything but probably should be strings or integers of similar width. A row consisting completely of None‘s is allowed.

INPUTS:

  • array – The array
  • with_lines – (Default: False) If True lines are drawn, if False they are not
  • align – (Default: 'b') Determines the alignment on the latex array environments

EXAMPLES:

sage: array=[[None, 2,3,4],[None,None],[5,6,7,8]]
sage: print sage.combinat.output.tex_from_skew_array(array)
\raisebox{-.6ex}{$\begin{array}[b]{*{4}c}\\
&\lr{2}&\lr{3}&\lr{4}\\
&\\
\lr{5}&\lr{6}&\lr{7}&\lr{8}\\
\end{array}$}
