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] ] to be specific the primary sort is on the the first column, and within the primary key, i would like to do a seconday sort of the matrix based on 2nd column .. does Numpy have this finctionality, or do part have to be programmed in Python ?? thanks; bob
