Member Enumeration Documentation

◆ coltype_t

enum coltype_t
Enumerator
NO_COLOUR 

do not colour connections

VAL_COLOUR 

use absolute value of matrix coefficients to determine colour

LOG_COLOUR 

use logarithm of absolute value instead

Member Function Documentation

◆ print() [1/2]

virtual void print ( const TCoordinate coord,
const std::vector< uint > &  label,
const std::string &  filename 
) const
virtual

print coordinates coord and colour coordinates with same label with same colour; the labels are defined by label and must begin with 0

◆ print() [2/2]

virtual void print ( const TCoordinate coord,
const TSparseMatrix S,
const std::string &  filename,
const coltype_t  col_type = TVTKCoordVis::NO_COLOUR 
) const
virtual

print coordinates coord and the connections between them as defined by the coefficients of the sparse matrix S

  • the ordering of S is assumed to be equal to coord
  • if log_scale is true, coefficient scaling is logarithmic
