逐行进行取最小值的操作,返回一个长度与输入参数行数相同的向量。
例子
m=matrix([4.5 2.6 1.5, 1.5 4.8 5.9, 4.9 2.0 NULL])
rowMin(m);
# output
[1.5,2,1.5]
t1=table(1..5 as x, 6..10 as y)
t2=table(5..1 as a, 10..6 as b);
rowMin(t1);
# output
[1,2,3,4,5]
rowMin(t1[`x], t2, take(2, 5));
# output
[1,2,2,2,1]
t=table(`AAPL`MS`IBM`IBM`C as sym, 49.6 29.46 29.52 30.02 174.97 as price1, 175.23 50.76 50.32 51.29 26.23 as price2);
select sym,rowMin(price1,price2) as min from t;
sym | min |
---|---|
AAPL | 49.6 |
MS | 29.46 |
IBM | 29.52 |
IBM | 30.02 |
