Hi,

I have two vectors for example:

A=[0 8 2 9 1 10 23]

B=[2 30 23 90 45 47 5]

I need to make chart where B is depending of A ( B=f(A) )

I sorted A vector using:

Asorted = sort(A,'ascend')

How to sort B vector to the elements corresponding to the values of A (before sorting)?

In the end i want to get vectors

Asorted=[0 1 2 8 9 10 23]

Bsorted=[2 45 23 30 47 5]

Second outout if sort() gives the index used to sort the vector. You can use it to arrange element of B.

A=[0 8 2 9 1 10 23];
B=[2 30 23 90 45 47 5];
[Asorted, idx] = sort(A,'ascend')
Bsorted = B(idx)

I see the problem- i make missprint: ixd instead of idx in [Asorted, idx].

Thank you and sorry for the confusion
