Sort data based on different column

  a = [5     8     1     2     7     6     3     4
       70    60    50    40    30    20    10     0]

I would like to sort the data based on the first row. [1 2 3 4 5 6 7 8 9 10;70 60 50 40 30 20 10 0];

I have tried using loops and the sort command but have had no luck. Could somebody help me figure out.

Try using the sortrows command in conjunction with a transpose. Apply it once to exploit column sorts (e.g. Column 1 is Row 1 above), and then again after the sort to put it back into the dimensions you want.

  a = [5     8     1     2     7     6     3     4
       70    60    50    40    30    20    10     0]
sorted_a = sortrows(a.',1).'
