Getting a point from a heatmap.

I create a heatmap, but would then like to be able to click a point and have this create a variable of the x and y labels at this point.

for example:

a = [ 0.7143 1.6667 1.2500 1.4286 0 0 0

0.7143 0 0 1.8750 1.4286 1.4286 2.5000

0 0 0.7143 0.5556 0.8333 0.7143 0

1.0000 0 0.7143 1.2500 0.7143 1.4286 0];

heatmap(a)

When I create this heatmap I can hover my mouse over a box to give the X and Y coordinates, but how can I click to create these as a variable?

Heatmap is a special plot that does not share the same set of properties as many other plots. For example, in a regular plot, you can right click anywhere on an axis and select "Export Cursor Data to Workspace" which will store the selected coordinate to a variable in your workspace. However, when you right click on a heatmap, nothing happens.

One way around this is to use imagesc() instead of heatmap() but then you lose some of the features that are helpful in heatmap().
