MATLAB: Sort from largest to smallest

Question

Dear all, I have this matrix:

A=[1  3
3  6
4  7
5  8
6  2
8  3
9  6]
Could you help me how to arrange the first colum from max to min

Answer 1

sort(A(:,1),'descend')

If you want to sort the matrix A by rows based on the first column, then e.g.

flipud(sortrows(A))

Or variations of the above based on what you want for output.
