matrix(Triangulation) -- the matrix whose columns are the points of a triangulation

• Function: matrix

• Usage:

  matrix T

• Inputs:
  • T, an instance of the type Triangulation,
• Optional inputs:
  • Degree => ..., default value null,
• Outputs:
  • a matrix, whose columns are the points (or vectors) of the configuration that $T$ triangulates
