    • Abstract
  • We put forward a new relational matrix,angular matrix.Preliminary research shows that the spectral method of graph is effective for representation and measurement of 2D spatial object's shape and the angular matrix can represent geometric shape of spatial object more accurately and precisely than other relational matrix,such as adjacent matrix,Laplacian matrix,and distance matrix.
