Further Examples: Ordering

Here is a list.

In[1]:=

This is the permutation that will put dd into sorted order.

In[2]:=

Out[2]=

Here is how to verify this.

In[3]:=

Out[3]=

You may only want to find the position of the maximum element.

In[4]:=

Out[4]=

Here is another way.

In[5]:=

Out[5]=

This gives the positions of the two largest elements in dd.

In[6]:=

Out[6]=

Here are the two largest elements.

In[7]:=

Out[7]=

This gives the ordering from largest to smallest.

In[8]:=

Out[8]=

This sorts the elements from largest to smallest.

In[9]:=

Out[9]=

Lists that are permutations of the numbers 1, 2, 3, , n can be composed using Part or [[]]. Here, for example, xx: 3 5 and yy: 5 1, so yyxx: 3 1.

In[10]:=

In[11]:=

In[12]:=

Out[12]=

Ordering gives the inverse of a permutation.

In[13]:=

Out[13]=

In[14]:=

Out[14]=

In[15]:=

Out[15]=

In[16]:=
