| This article is about a function from ApCoCoA-1. |
NCo.AdMatrix
Construct an adjacency matrix of the Ufnarovski graph for a finite set of words.
Syntax
NCo.AdMatrix(X:STRING, M:LIST):LIST
Description
Please note: The function(s) explained on this page is/are using the ApCoCoAServer. You will have to start the ApCoCoAServer in order to use it/them.
@param X: alphabet (or set of indeterminates) generating the free monoid K<X>. It is of STRING type.
@param M: a LIST of words (or terms) in <X> which generates the monoid ideal <M>. Each word is represented as a STRING. For example, xy^2x is represented as "xyyx", and the identity is represented as the empty string "".
@return: a LIST consisting of two elements. The first element in the LIST is a LIST of words that are the vertices in the Ufnarovski graph of M, and the second element is an adjacency matrix of the Ufnarovski graph.
Example
X:="xy"; M:=["xxx","yxy","xyx"]; NCo.AdMatrix(X, M); [["xx", "xy", "yx", "yy"], Mat([ [0, 1, 0, 0], [0, 0, 0, 1], [1, 0, 0, 0], [0, 0, 1, 1] ])] ------------------------------- X:="xy"; M:=["xxx","yxy","xyx","yyx","yyy"]; NCo.AdMatrix(X, M); [["xx", "xy", "yx", "yy"], Mat([ [0, 1, 0, 0], [0, 0, 0, 1], [1, 0, 0, 0], [0, 0, 0, 0] ])] -------------------------------
