rowMax

rowMax(args...)

row 系列函数通用参数说明和计算规则请参考：rowFunctions

逐行进行取最大值的操作，返回一个长度与输入参数行数相同的向量。

m=matrix([4.5 2.6 1.5, 1.5 4.8 5.9, 4.9 2.0 NULL])
rowMax(m);

返回：[4.9,4.8,5.9]

t1=table(1..5 as x, 6..10 as y)
t2=table(5..1 as a, 10..6 as b);

rowMax(t1);

返回：[6,7,8,9,10]

rowMax(t1[`y], t2, take(8, 5));

返回：[10,9,8,9,10]

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,rowMax(price1,price2) as max from t;

返回：
