Sort a matrix according to the index of a vector

I have following labels for the rows and columns of a square matrix:
labels = {'dog', 'car', 'fish'}'
The corresponding matrix that expresses the semantic similarity between the terms is
D = [[0 0.8 0.2];
[0.8 0 0.7];
[0.2 0.7 0]];
I want to sort matrix and labels after following index
idx = [1 2 1];
Sorting the labels is easy:
[values,isort]=sort(idx);
labels_sort = labels(isort)
labels_sort =
3×1 cell array
{'dog' }
{'fish'}
{'car' }
But how can i sort the matrix D accordingly?
