FUNCTION: Table2Bna - convert a table into an element of any Bn-algebra

CALLING SEQUENCE:

Table2Bna(t)

BNA[Table2Bna](t)

PARAMETERS:

t = any table denoting an element of any Bn-algebra

SYNOPSIS:

• The Table2Bna function converts a table into an element of any Bn-algebra. The table should be indexed by codes of Bn and each entry corresponding to a code cod is interpreted as the coefficient of cod in the expression of the element e.

• Whenever there is a conflict between the function name Table2Bna and another name used in the same session, use the long form BNA['Table2Bna'].

EXAMPLES:

> with(BNA):
> t:=table([[0,2,1]=x1+x2, [0,2,2]=x1^2, [0,0,0]=1]);
 
                          t := table([
                                 [0, 2, 1] = x1 + x2
                                               2
                                 [0, 2, 2] = x1
                                 [0, 0, 0] = 1
                               ])
 
> Table2Bna(t);
 
                                                    2
              (x1 + x2) B[0, 2, 1] + B[0, 0, 0] + x1  B[0, 2, 2]
