how to reverse "sort"

For example we have a row like

m=[1 6 2 8 9] [Y,I] = sort(m)

then it gives you

Y =

     1     2     6     8     9

I =

     1     3     2     4     5

But I would like to sort them from big number to small

Hi,

There is an extra optional argument that will do that:

>> m=[1 6 2 8 9]; [Y,I] = sort(m,'descend')

Y =

       9     8     6     2     1

I =

       5     4     2     3     1

Hi, have you read the documentation for sort()?

    m = [1 6 2 8 9];
    [Y,I] = sort(m,'descend');
