Sorting 3 structures together

Please, I have 3 structures as follows:

x_loc.xx=[3.0, 5.1, 6.5] % x-coordinate

y_loc.yy=[0.5, 1.4, 3.2] % y-coordintates

cash.bb=[14, 1, 6]

I want to sort the structure 'cash' from smallest to biggest. The sorting should also sort the x and coordinates (x_loc.xx and y_loc.yy).

i.e I want the answer to be:

cash.bb=[1,6,14]

x_loc.xx=[5.1, 6.5, 3.0]

y_loc.xx=[1.4, 3.2,0.5].

I coluldnt think of how to start.... pls help

Thanks in anticipation

"I coluldnt think of how to start...."

If you want to sort something, the best place to start is to read the sort documentation. Then you would learn that sort has a second output argument, which are indices that you can use to sort any other arrays that you want:

[cash.bb,idx] = sort(cash.bb)
x_loc.xx = x_loc.xx(idx)
y_loc.yy = y_loc.yy(idx)

Note: having separate structures named x_loc and y_loc does not seem to be a very efficient way to arrange your data.

I changed them to the same structure:

cash.bb

x_loc.bb

y_loc.bb

it works.

"I changed them to the same structure:"

cash.bb
x_loc.bb
y_loc.bb

Nope. Those are still three separate structures.
