Order all the rows based on one row.

Hi!

   I´ve searching for an answer but I didn´t find any, and before programming a super inefficient function I just wanted to be sure that there weren´t any prebuilt function to do this. So the question is:

How do you sort all the rows of a matrix based on one specific row. For example, based on the first row:

LENGTH =

         723        1081         860
           1           2           3

Sorted:

LENGTH =

         723         860        1081
           1           3           2

Thank you in advance!

Use the sortrows() command.

You are actually sorting columns, so you will need to transpose your array, then sort, then transpose back:

sorted_L = sortrows(L',1)'

That worked!! I don´t know why I didn´t think on that... ¬¬

Thank you for the super fast answer!
