how can ı sort of the matrices

ı want to sort to this matrice like this but ı dont know how can ı do that? help me pls.

[dpb]

No idea -- what's the original form and what's the rule?

Attach the actual data, not pictures.

ı am trying to do knn algorithm and these are distances of my point so ı have two class(A and B) and ı determine the class of values as 1 and 2(row 2). so now ı am trying to put in order these values but ı gotta move them together.

Do you have the Statistic and Machine Learning Toolbox? Did you use knnsearch()? See attached demo.

[mts]

no ı dont have any of them, also my code attached , so how can ı add sort function or put ın an order these values as ı want at first post

Transpose distance so that it has 2 columns. Then call sortrows().

sortedDistances = sortrows(distance', 1);

thank you 'ımage analyst'.İt works but ı dont understand that why did we get transpose of matrice

[Image Analyst]

sortrows moves rows together, all columns in lock-step. That's what we want. We do not want to sort the original first row, and then the second row. However the first row gets repositioned, we want the second row to follow along in the very same order. sortrows() takes care of that for you but the data has to be in rows.

ı understand now. thank you for your help.
