I am new to numpy. I have 2 questions for array sort.
1. How to sort an array by its one column or one row?
I know python build-in sort() can do it for list by passing own cmp
function. but array function sort() will sort each column or row
seperately,as I know. I don't want to convert array to list to sort and
then convert back to array.
2. How to get the rank of a rank-0 array? The first "rank" means the
order of each element after sorting, instead of the "dimension" meaning
in numpy. Just like "rank()" function in splus.
