q)array2: 6 7 8 9 10;
q)array1,'array2

Could also

flip (array1;array2)


If you want to pass each element of array1 & array2 to a function directly then each-both can be used :

array1

array2

each-both

q)array1: 1 2 3 4 5;
q)array2: 6 7 8 9 10;
q)f:{x,y}
q)f'[array1;array2]
(1j, 6j;2j, 7j;3j, 8j;4j, 9j;5j, 10j)
