Thread Subject: How to sort the data by the index value?

Dear Sir or Madam,

I'd like to sort the data by the index value with
ascending order and assume that there is a matrix A,
including 4 tuples:

A:
[ 0.3 0.7 0.9
 -0.2 1.1 0.8
  0.6 -0.1 -0.7
  0.1 0.3 -0.2 ]

In A, each row is a tuple (index value, data1, data2)
Then, I'd like to sort each tuple with by the index
value with ascending order.

Also, it can be describred by A':

[ -0.2 1.1 0.8
   0.1 0.3 -0.2
   0.3 0.7 0.9
   0.6 -0.1 -0.7 ]

Therefore, how can I transform A into A' by Matlab codes?
Thank you so much!!

sortrows(A);
