If I have two arrays A and B as displayed below, how can I rearrange B such that a new boolean array Ba which corresponds to the values of array B can be resorted according to the values of array A instead?
For example, if I have:
A =
1 5 3 2 4 4 2 2 3 5
2 1 1 2 0 1 1 1 0 0
30 22 23 25 -1 30 18 25 -1 -1
B =
1 2 2 2 3 3 4 4 5 5
2 1 1 2 0 1 0 1 0 1
30 18 25 25 -1 23 -1 30 -1 22
Ba =
0 0 1 0 1 0 0 0 0 0
Note that array B is simply the sorted version of array A according to the first row in an ascended order. It is resorted twice according to the second row in an ascended order for the values in row 1 that equal one another (e.g., if there are multiples elements equal to 3 in row 1, then the array will sort by the second row instead, so if the second row has values 3 3 3 3 3; 2 6 3 9 1, it will then be sorted to 3 3 3 3 3; 1 2 3 6 9)
I only mentioned this in case reverse sorting might work easier than entirely rearranging the position of the array.
I want to rearrange array B and Ba such that it corresponds to the positioning of array A.
So the new arrays would look like this:
A =
1 5 3 2 4 4 2 2 3 5
2 1 1 2 0 1 1 1 0 0
30 22 23 25 -1 30 18 25 -1 -1
Aa =
0 0 0 0 0 0 0 1 1 0
The new array would essentially match A, and the array Aa is the same array Ba but now rearranged so that it follows the arrangement of A rather than B.
I am not entirely sure how to write the MATLAB code to accomplish this.
