Hi;
 i am having trouble trying to sort the rows of a 2 dimensional array by the
values in the first column .. does anybody know how or have an example of
how to do this ??? while leaving the remain columns remain relative to the
leading column

from numpy import *

a=array( [ [4, 4, 3], [4, 5, 2],  [3, 1, 1] ] )

i would like to generate the output (or get the output ...)

b = [ [3,1,1], [4,4,3], [4,5,2] ]

thanks;
bob
