Hi, group, 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.
Thank you
