7.7.3.0. variablesStandard
Procedure from library central.lib (see central_lib).

Usage:
variablesStandard();

Return:
ideal, generated by algebra variables

Purpose:
computes the set of algebra variables taken in their natural order

Example:
 
LIB "central.lib";
ring AA = 0,(x,y,z),dp;
matrix D[3][3]=0;
D[1,2]=-z;  D[1,3]=2*x;  D[2,3]=-2*y;
def A = nc_algebra(1,D); setring A; // this algebra is U(sl_2)
// Variables in their natural order:
variablesStandard();
==> _[1]=x
==> _[2]=y
==> _[3]=z
