I'm trying to come up with a verb that would return the sort order of a
table according to criteria, such as one column can sort up, the other
down, etc. However, I can't seem to figure it out. Please help me (see
example below).
Given the dyadic verb MultiSort (where the left argument being 0 means
sort up, and 1 means sort down):
n =. >1 4 72; 2 6 41; 1 4 20; 1 5 74; 1 6 27
n
1 4 72
2 6 41
1 4 20
1 5 74
1 6 27
]isortorder =. 0 1 0 MultiSort n
4 3 2 0 1
isortorder { n
1 6 27
1 5 74
1 4 20
1 4 72
2 6 41
Thanks,
Martin
