How to sort heatmap columns based on outside data

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.

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));
