Shouldn't jobu = 'f' and jobu = 'r' be included here too?

Yes. I got it hard to understand the shape of U with jobu = 'f' and jobu = 'r', so these was remained for later implementation. For jobu = 'r', how many cols should be included(as numrank is determined inside lapack), or using the maxium(MIN(m,n)) is OK?

Since the jobu = 'a', 's', 'u', 'r', 'f' conditional is repeated several times, it may be worth to declare an ancillary variable to wrap the status. An analogous comment applies to jobv.
