>>> nat = Axis('nat=BE,FO')
>>> sex = Axis('sex=M,F')
>>> sex2 = Axis('sex=U')
>>> xtype = Axis('type=type1,type2')
>>> arr1 = ones([sex, xtype])
>>> arr1
sex\type  type1  type2
       M    1.0    1.0
       F    1.0    1.0
>>> arr2 = zeros([sex2, xtype])
>>> arr2
sex\type  type1  type2
       U    0.0    0.0
>>> arr1.extend(X.sex, arr2)
sex\type  type1  type2
       M    1.0    1.0
       F    1.0    1.0
       U    0.0    0.0
>>> arr3 = zeros([sex2, nat])
>>> arr3
sex\nat   BE   FO
      U  0.0  0.0
>>> arr1.extend(X.sex, arr3)
sex  type\nat   BE   FO
  M     type1  1.0  1.0
  M     type2  1.0  1.0
  F     type1  1.0  1.0
  F     type2  1.0  1.0
  U     type1  0.0  0.0
  U     type2  0.0  0.0
