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;
```
