list manipulation - Sort rows in a matrix with a vector

Let's suppose I have a matrix:

$A=\left[\begin{array}{ccc} a & b & c\\ d & e & f\\ g & h & i \end{array}\right]$

and I want to sort the rows using a sort-vector:

$sortVec=\left[\begin{array}{c} 1\\ 3\\ 2 \end{array}\right]$

This would mean that my second row in matrix A would need to be placed at row number 3 and the thrid row would need to be placed at row number 2.

Outcome:

$A=\left[\begin{array}{ccc} a & b & c\\ g & h & i\\ d & e & f \end{array}\right]$

How can I do it in Mathematica?

my question aims at a simple solution. As far as I can see, it is not a duplicate of "Elegant operations on matrix rows and columns".

Answer

You are asking for a permutation, so use Permute

m = Partition[Symbol /@ CharacterRange["a", "i"], 3]

{{a, b, c}, {d, e, f}, {g, h, i}}

Permute[m, {1, 3, 2}]

{{a, b, c}, {g, h, i}, {d, e, f}}
