Re: Apply a list of parameters to a list of input

[cillianreilly]

The lambda isn’t necessary here:

 

q)update m:price@'n from tab 
time        | price n m 
------------| --------------------------------- 
10:03:54.347| 20.83 21.44 26.83 29.83 0 20.83e 
10:04:05.827| 88.88 88.75 83.27 823.77 1 88.75

 

Not useful for the general case, but here you can forgo the explicit n column and use the virtual index column instead:

 

q)tab:([time:10:03:54.347 10:04:05.827]price:(20.83 21.44 26.83 29.83e;88.88 88.75 83.27 823.77f)) 
q)update m:price@'i from tab 
time        | price m 
------------| ------------------------------- 
10:03:54.347| 20.83 21.44 26.83 29.83 20.83e 
10:04:05.827| 88.88 88.75 83.27 823.77 88.75
