Hi,
I plotted a heatmap as shown below:
h = heatmap(array);
I want to sort my columns based on some outside data, specifically an array called idx shown below. How can I do this?
Thanks.

Ran in:
array = rand(13,28);
idx = [13 5 24 23 17 15 3 12 1 25 26 4 18 10 27 14 21 7 20 19 8 28 11 2 6 22 16 9];
h = heatmap(array(:,idx),'XDisplayLabels',sprintfc('%d',idx));
