Assume a 10 x 3 matrix. Column 1 contains decimal numbers from +1.000 to -1.000. Columns 2 & 3 contain integers. How can I create a new 10 x 3 matrix with the numbers in column 1 arranged from +1 at top to -1 at the bottom?

Rearrange 10 x 3 matrix so first column decimal numbers are arranged in descending order of magnitude from +1.0 to -1.0

>> A = [0.6,2,4;-0.2,5,3;1,3,8;-1,5,2];
>> sortrows(A,-1)
ans =
1 3 8
0.6 2 4
-0.2 5 3
-1 5 2
