Description:
Compute the ordinal numbers of an integer’s members in another integer sequence.
Syntax:
p.inv(k)
Note:
The function returns the ordinal numbers of the members from 1 to k in integer sequence p. Return 0 for the numbers that do not exist in p.
Parameter:
|
p |
An integer sequence |
|
k |
An integer, which is by default the length of p |
Return value:
An integer sequence composed of the ordinal numbers of the integers from 1 to k in integer sequence p
Example:
|
|
A |
|
|
1 |
=[1,3,5,7] |
|
|
2 |
=A1.inv(4) |
Among the four numbers 1, 2, 3 and 4, the ordinal numbers of 1 and 3 in sequence A1 are 1 and 2. 2 and 4 do not exist in sequence A1, so their ordinal numbers are 0. [1,0,2,0] is returned finally. |
