Sort cells order according to their values?

Hi all,

I have a function produces a cell like this:

K>> otpt{:}
ans =
     3     0
     2     1
ans =

              1           -1
              4         -0.5
  ans =
              4         -0.5
              3            0

In each cell, the first column are labels and second column are x-coordinate of nodes. The output is a division of [-1, 1] into a number of blocks. As you can see this example equals to

The labels remain fixed for the nodes, however each time the function gives different order of cells. Now whenever I get the output, I'd like to sort the order of cells from left to right, i.e. I want the output to be

K>> otpt{:}

    ans =

                1           -1
                4         -0.5
    ans =
                4         -0.5
                3            0

ans =
       3     0
       2     1

How can I do it? Thanks!

I'm not sure why your desired output is being spread over two function outputs, but I believe you should be using the "sort" function with the optional second output in this scenario.

syntax:

[B,IX] = sort(A)

In your scenario, I'll assume you can do the sort inside your function on a common variable. I'll call that variable "list". You want to sort the variables in the second column of the variable.

[B2,IX] = sort(list(:,2));
B1 = list(IX,1);
output = [B1,B2];

After that you can parse the variable "output" as necessary to get your multiple outputs.
