Sort & Permutation

Posted 10 years ago

Greetings,

I would like to obtain the permutation resulting from the sorting of the given list (as opposed to the sorted list):

input = {5.3, 2.7, 9.2, 0.0}
output = {0.0, 2.7, 5.3, 9.2}
Desired Output = {4, 2, 1, 3}

Thanks in advance

In[17]:= input = {5.3, 2.7, 9.2, 0.0}

Out[17]= {5.3, 2.7, 9.2, 0.}

In[18]:= Ordering[input, 4]

Out[18]= {4, 2, 1, 3}

Ordering does this.
