rowAnd

rowAnd(args...)

row 系列函数通用参数说明和计算规则请参考：rowFunctions

逐行进行逻辑与操作，返回一个长度与输入参数行数相同的向量。

m=matrix([true false false, true true true, true true true])
rowAnd(m);
# output
[1,0,0]

t1=table(false true true true false as x, false true false true true as y)
rowAnd(t1);
# output
[0,1,0,1,0]

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)
# output

select *  from t where rowAnd(price1>30, price2>50);
