语法

rowMin(args…)

row 系列函数通用参数说明和计算规则请参考: 行计算系列（row 系列）

详情

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);
[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);
 [1,2,3,4,5]

$ rowMin(t1[`x], t2, take(2, 5));
[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
C	26.23
