Hi! I need to sort matrix A from least to greatest; however, the values are tied to matrix B. How can I can make B adjust with a matrix A sort.
Matrix A and B are the starting values, and A' and B' are the desired answer.
A = [ 2, 3, 1, 4]
B = [ 6, 5, 1, 10]
A' = [ 1, 2 , 3, 4]
B' = [ 1, 6, 5, 10]

Use the 2nd output argument of the sort( ) function, which has the indexing. E.g.,
[Asorted,ix] = sort(A);
Bsorted = B(ix);
