Hi, I would ideally like to sort an multidimensional array by the first column, but I can only manage to adjust the whole array. For example...
a = array([(1,0,2,5),(1,5,6,2),(1,2,8,7),(1,4,4,6),(1,3,2,3),(1,11,2,0),(1,10,1,3),(1,9,0,4),(1,8,9,6)]) a array([[ 1, 0, 2, 5], [ 1, 5, 6, 2], [ 1, 2, 8, 7], [ 1, 4, 4, 6], [ 1, 3, 2, 3], [ 1, 11, 2, 0], [ 1, 10, 1, 3], [ 1, 9, 0, 4], [ 1, 8, 9, 6]]) sort(a, axis = 0) array([[ 1, 0, 0, 0], [ 1, 2, 1, 2], [ 1, 3, 2, 3], [ 1, 4, 2, 3], [ 1, 5, 2, 4], [ 1, 8, 4, 5], [ 1, 9, 6, 6], [ 1, 10, 8, 6], [ 1, 11, 9, 7]])
When really what i wanted was not for the 3rd and 4th columns to also be sorted nunmerically in that way. In unix I would reformat the first two columns in gawk i.e. gawk '{printf("%2.3d %2.3d, %d, %d\n", $1, $2, $3, $4)}' | sort -n -k 1 Any help would be appreciated! Thanks Martin
