Detailed Description

Angle structures on triangulations.

Function Documentation

NMatrixInt * regina::makeAngleEquations ( const NTriangulation *  tri)

Creates a new set of angle structure equations for the given triangulation.

Each equation will be represented as a row of the matrix, and each column will represent a coordinate in the underlying coordinate system (which is described in the NAngleStructureVector class notes).

The returned matrix will be newly allocated and its destruction will be the responsibility of the caller of this routine.

This routine is identical to the static class method NAngleStructureVector::makeAngleEquations(). It is offered again here as a global routine so that it is accessible to Python users (who cannot access the NAngleStructureVector class).
